The Data Surrounding Higher Education and COVID-19

Just a few short weeks ago, it would have seemed impossible for some microscopic pathogen to upend our lives as we knew it, but the novel Coronavirus has proven us breathtakingly wrong.

It has suddenly and unexpectedly changed everything we had thought was most stable and predictable in our lives, from the ways that we work to the ways we interact with one another. It’s even changed the way we learn, as colleges and universities across the nation shutter their doors.

But what is the real impact of COVID-19 on higher education? How are college students really faring in the face of the pandemic, and what can we do to support them now and in the post-pandemic life to come?

The Scramble is On

Probably the most significant challenge that schools, educators, and students alike are facing is that no one really saw this coming, so now we’re trying to figure out how to protect students’ education while also protecting their physical health. We’re having to make decisions that impact millions of students and faculty and do that with no preparation whatsoever.

To make matters worse, faculties are having to convert their classes to a forum the majority have never even used before. Before the lockdown, more than 70% of faculty in higher education had zero experience with online teaching. Now they’re being asked to convert their entire semester’s course schedule from an in-class to an online format, and they’re having to do it in a matter of weeks if not days.

For students who’ve never taken a distance learning course before, these impromptu, online, cobbled-together courses are hardly the recipe for academic success. The challenge is even greater for lab-based courses, where content mastery depends on hands-on work and laboratory applications. To solve this problem, some of the newly-minted distance ed instructors are turning to online lab simulations to help students make do until the real thing is open to them again.

Making Do

It’s not just the schools and the faculty that have been caught off guard by the sudden need to learn while under lockdown. Students are also having to hustle to make sure they have the technology they need to move their college experience online. Unfortunately, for many students, that’s not always easy, and for some, it’s downright impossible.

Studies show that large swaths of the student population: first-generation college students, community college students, immigrants, and lower-income students, typically rely on on-campus facilities to access the technology they need to do their work. When physical campuses close and the community libraries and hotspots with them, so too does the chance for many students to take their learning online.

Students in urban environments face particular risks. Even if they are able to access the technology they need to engage in distance learning, they may find it impossible to socially isolate. The need to access a hotspot or wi-fi connection might put them in unsafe proximity to other students, not to mention the millions of workers now forced to telecommute.

The Good News

America’s millions of new online learners and teachers may have a tough row to hoe, but the news isn’t all bad. Online education is by no means a new thing. By 2017, nearly 7 million students were enrolled in at least one distance education course according to a recent survey by the National Center for Education Statistics.

It isn’t as though the technology to provide a secure, user-friendly learning experience doesn’t exist. The financial industry, for example, has played a leading role in developing private, responsive, and highly-customizable technology solutions to meet practically any need a client or stakeholder may have.

The solutions used for the financial sector can be built on and modified for the online learning experience to ensure the privacy of students, educators, and institutions while providing real-time access to learning tools and content to classmates and teachers.

A New Path?

As challenging as it may be, transitioning to online learning not only offers opportunities for the present, but it may well open up new paths for the future. While our world may finally be approaching the downward slope of the curve and while we may be seeing the light at the end of the tunnel, until there’s a vaccine, we haven’t likely seen the last of COVID-19.

And even when we lay the COVID beast to rest, infectious disease, unfortunately, is a fact of human life. For students just starting to think about their career paths, this lockdown may well be the push they need to find a career that’s well-suited to this “new normal.”

For instance, careers in data science transition perfectly from onsite to at-home work, and as epidemiological superheroes like Dr. Fauci and Dr. Birx have shown, they are often involved in important, life-saving work. These are also careers that can be pursued largely, if not exclusively, online. Whether you’re a complete newbie or a veteran to the field, there is a large range of degree and certification programs available online to launch or advance your data science career.

It might be that your college-with-corona experience is pointing your life in a different direction, toward education rather than data science. With a doctorate in education, your future career path is virtually unlimited. You might find yourself teaching, researching, leading universities or developing education policy.

What matters most is that with an EdD, you can make a difference in the lives of students and teachers, just as your teachers and administrators are making a difference in your life. You can be the guiding and comforting force for students in a time of crisis and you can use your experiences today to pay it forward tomorrow.

Interview: Künstliche Intelligenz in der Pharma-Forschung und -Entwicklung

Interview mit Anna Bauer-Mehren, Head of Data Science in der Pharma-Forschung und -Entwicklung bei Roche in Penzberg

Frau Dr. Bauer-Mehren ist Head of Data Science im Bereich Pharma-Forschung und -Entwicklung bei Roche in Penzberg. Sie studierte Bioinformatik an der LMU München und schloss ihre Promotion im Bereich Biomedizin an der Pompeu Fabra Universität im Jahr 2010 in Spanien ab. Heute befasst sie sich mit dem Einsatz von Data Science zur Verbesserung der medizinischen Produkte und Prozesse bei Roche. Ferner ist sie Speaker der Predictive Analytics World Healthcare (Virtual Conference, Mai 2020).

Data Science Blog: Frau Bauer-Mehren, welcher Weg hat Sie bis an die Analytics-Spitze bei Roche geführt?

Ehrlich gesagt bin ich eher zufällig zum Thema Data Science gekommen. In der Schule fand ich immer die naturwissenschaftlich-mathematischen Fächer besonders interessant. Deshalb wollte ich eigentlich Mathematik studieren. Aber dann wurde in München, wo ich aufgewachsen und zur Schule gegangen bin, ein neuer Studiengang eingeführt: Bioinformatik. Diese Kombination aus Biologie und Informatik hat mich so gereizt, dass ich die Idee des Mathe-Studiums verworfen habe. Im Bioinformatik-Studium ging es unter anderem um Sequenzanalysen, etwa von Gen- oder Protein-Sequenzen, und um Machine Learning. Nach dem Masterabschluss habe ich an der Universitat Pompeu Fabra in Barcelona in biomedizinischer Informatik promoviert. In meiner Doktorarbeit und auch danach als Postdoktorandin an der Stanford School of Medicine habe ich mich mit dem Thema elektronische Patientenakten beschäftigt. An beiden Auslandsstationen kam ich auch immer wieder in Berührung mit Themen aus dem Pharma-Bereich. Bei meiner Rückkehr nach Deutschland hatte ich die Pharmaforschung als Perspektive für meine berufliche Zukunft fest im Blick. Somit kam ich zu Roche und leite seit 2014 die Abteilung Data Science in der Pharma-Forschung und -Entwicklung.

Data Science Blog: Was sind die Kernfunktionen der Data Science in Ihrem Bereich der Pharma-Forschung und -Entwicklung?

Ich bin Abteilungsleiterin für Data Science von pREDi (Pharma Research and Early Development Informatics), also von Roches Pharma-Forschungsinformatik. Dieser Bereich betreut alle Schritte von der Erhebung der Daten bis zur Auswertung und unterstützt alle Forschungsgebiete von Roche, von den Neurowissenschaften und der Onkologie bis hin zu unseren Biologie- und Chemielaboren, die die Medikamente herstellen. Meine Abteilung ist für die Auswertung der Daten zuständig. Wir beschäftigen uns damit, Daten so aufzubereiten und auszuwerten, dass daraus neue Erkenntnisse für die Erforschung und Entwicklung sowie die Optimierung von pharmazeutischen Produkten und Therapien gewonnen werden könnten. Das heißt, wir wollen die Daten verstehen, interpretieren und zum Beispiel einen Biomarker finden, der erklärt, warum manche Patienten auf ein Medikament ansprechen und andere nicht.

Data Science Blog: Die Pharmaindustrie arbeitet schon seit Jahrzehnten mit Daten z. B. über Diagnosen, Medikationen und Komplikationen. Was verbessert sich hier gerade und welche Innovationen geschehen hier?

Für die medizinische Forschung ist die Qualität der Daten sehr wichtig. Wenn ein Medikament entwickelt wird, fallen sehr große Datenmengen an. Früher hat niemand dafür gesorgt, dass diese Daten so strukturiert und aufbereitet werden, dass sie später auch in der Forschung oder bei der Entwicklung anderer Medikamente genutzt werden können. Es gab noch kein Bewusstsein dafür, dass die Daten auch über den eigentlichen Zweck ihrer Erhebung hinaus wertvoll sein könnten. Das hat sich mittlerweile deutlich verbessert, auch dank des Bereichs Data Science. Heute ist es normal, die eigenen Daten „FAIR“ zu machen. Das Akronym FAIR steht für findable, accessible, interoperable und reusable. Das heißt, dass man die Daten so sauber managen muss, dass Forscher oder andere Entwickler sie leicht finden, und dass diese, wenn sie die Berechtigung dafür haben, auch wirklich auf die Daten zugreifen können. Außerdem müssen Daten aus unterschiedlichen Quellen zusammengebracht werden können. Und man muss die Daten auch wiederverwenden können.

Data Science Blog: Was sind die Top-Anwendungsfälle, die Sie gerade umsetzen oder für die Zukunft anstreben?

Ein Beispiel, an dem wir zurzeit viel forschen, ist der Versuch, so genannte Kontrollarme in klinischen Studien zu erstellen. In einer klinischen Studie arbeitet man ja immer mit zwei Patientengruppen: Eine Gruppe der Patienten bekommt das Medikament, das getestet werden soll, während die anderen Gruppe, die Kontrollgruppe, beispielsweise ein Placebo oder eine Standardtherapie erhält. Und dann wird natürlich verglichen, welche der zwei Gruppen besser auf die Therapie anspricht, welche Nebenwirkungen auftreten usw. Wenn wir jetzt in der Lage wären, diesen Vergleich anhand von schon vorhanden Patientendaten durchzuführen, quasi mit virtuellen Patienten, dann würden wir uns die Kontrollgruppe bzw. einen Teil der Kontrollgruppe sparen. Wir sprechen hierbei auch von virtuellen oder externen Kontrollarmen. Außerdem würden wir dadurch auch Zeit und Kosten sparen: Neue Medikamente könnten schneller entwickelt und zugelassen werden, und somit den ganzen anderen Patienten mit dieser speziellen Krankheit viel schneller helfen.

Data Science Blog: Mit welchen analytischen Methoden arbeiten Sie und welche Tools stehen dabei im Fokus?

Auch wir arbeiten mit den gängigen Programmiersprachen und Frameworks. Die meisten Data Scientists bevorzugen R und/oder Python, viele verwenden PyTorch oder auch TensorFlow neben anderen.  Generell nutzen wir durchaus viel open-source, lizenzieren aber natürlich auch Lösungen ein. Je nachdem um welche Fragestellungen es sich handelt, nutzen wir eher statistische Modelle- Wir haben aber auch einige Machine Learning und Deep Learning use cases und befassen uns jetzt auch stark mit der Operationalisierung von diesen Modellen. Auch Visualisierung ist sehr wichtig, da wir die Ergebnisse und Modelle ja mit Forschern teilen, um die richtigen Entscheidungen für die Forschung und Entwicklung zu treffen. Hier nutzen wir z.B. auch RShiny oder Spotfire.

Data Science Blog: Was sind Ihre größten Herausforderungen dabei?

In Deutschland ist die Nutzung von Patientendaten noch besonders schwierig, da die Daten hier, anders als beispielsweise in den USA, dem Patienten gehören. Hier müssen erst noch die notwendigen politischen und rechtlichen Rahmenbedingungen geschaffen werden. Das Konzept der individualisierten Medizin funktioniert aber nur auf Basis von großen Datenmengen. Aktuell müssen wir uns also noch um die Fragen kümmern, wo wir die Datenmengen, die wir benötigen, überhaupt herbekommen. Leider sind die Daten von Patienten, ihren Behandlungsverläufen etc. in Deutschland oft noch nicht einmal digitalisiert. Zudem sind die Daten meist fragmentiert und auch in den kommenden Jahren wird uns sicherlich noch die Frage beschäftigen, wie wir die Daten so sinnvoll erheben und sammeln können, dass wir sie auch integrieren können. Es gibt Patientendaten, die nur der Arzt erhebt. Dann gibt es vielleicht noch Daten von Fitnessarmbändern oder Smartphones, die auch nützlich wären. Das heißt, dass wir aktuell, auch intern, noch vor der Herausforderung stehen, dass wir die Daten, die wir in unseren klinischen Studien erheben, nicht ganz so einfach mit den restlichen Datenmengen zusammenbringen können – Stichwort FAIRification. Zudem reicht es nicht nur, Daten zu besitzen oder Zugriff auf Daten zu haben, auch die Datenqualität und -organisation sind entscheidend. Ich denke, es ist sehr wichtig, genau zu verstehen, um was für Daten es sich handelt, wie diese Erhoben wurden und welche (wissenschaftliche) Frage ich mit den Daten beantworten möchte. Ein gutes Verständnis der Biologie bzw. Medizin und der dazugehörigen Daten sind also für uns genauso wichtig wie das Verständnis von Methoden des Machine Learning oder der Statistik.

Data Science Blog: Wie gehen Sie dieses Problem an? Arbeiten Sie hier mit dedizierten Data Engineers? Binden Sie Ihre Partner ein, die über Daten verfügen? Freuen Sie sich auf die Vorhaben der Digitalisierung wie der digitalen Patientenakte?

Roche hat vor ein paar Jahren die Firma Flatiron aus den USA übernommen. Diese Firma bereitet Patientendaten zum Beispiel aus der Onkologie für Krankenhäuser und andere Einrichtungen digital auf und stellt sie für unsere Forschung – natürlich in anonymisierter Form – zur Verfügung. Das ist möglich, weil in den USA die Daten nicht den Patienten gehören, sondern dem, der sie erhebt und verwaltet. Zudem schaut Roche auch in anderen Ländern, welche patientenbezogenen Daten verfügbar sind und sucht dort nach Partnerschaften. In Deutschland ist der Schritt zur elektronischen Patientenakte (ePA) sicherlich der richtige, wenn auch etwas spät im internationalen Vergleich. Dennoch sind die Bestrebungen richtig und ich erlebe auch in Deutschland immer mehr Offenheit für eine Wiederverwendung der Daten, um die Forschung voranzutreiben und die Patientenversorgung zu verbessern.

Data Science Blog: Sollten wir Deutsche uns beim Datenschutz lockern, um bessere medizinische Diagnosen und Behandlungen zu erhalten? Was wäre Ihr Kompromiss-Vorschlag?

Generell finde ich Datenschutz sehr wichtig und erachte unser Datenschutzgesetz in Deutschland als sehr sinnvoll. Ich versuche aber tatsächlich auf Veranstaltungen und bei anderen Gelegenheiten Vertreter der Politik und der Krankenkassen immer wieder darauf aufmerksam zu machen, wie wichtig und wertvoll für die Gesellschaft eine Nutzung der Versorgungsdaten in der Pharmaforschung wäre. Aber bei der Lösung der Problematik kommen wir in Deutschland nur sehr langsam voran. Ich sehe es kritisch, dass viel um dieses Thema diskutiert wird und nicht einfach mal Modelle ausprobiert werden. Wenn man die Patienten fragen würde, ob sie ihre Daten für die Forschung zur Verfügung stellen möchte, würden ganz viele zustimmen. Diese Bereitschaft vorher abzufragen, wäre technisch auch möglich. Ich würde mir wünschen, dass man in kleinen Pilotprojekten mal schaut, wie wir hier mit unserem Datenschutzgesetz zu einer ähnlichen Lösung wie beispielsweise Flatiron in den USA kommen können. Ich denke auch, dass wir mehr und mehr solcher Pilotprojekte sehen werden.

Data Science Blog: Gehört die Zukunft weiterhin den Data Scientists oder eher den selbstlernenden Tools, die Analysen automatisiert für die Produkt- oder Prozessverbesserung entwickeln und durchführen?

In Bezug auf Künstliche Intelligenz (KI) gibt es ein interessantes Sprichwort: Garbage in, Garbage out. Wenn ich also keine hochqualitativen Daten in ein Machine Learning Modell reinstecke, dann wird höchstwahrscheinlich auch nichts qualitativ Hochwertiges rauskommen. Das ist immer die Illusion, die beim Gedanken an KI entsteht: Ich lass einfach mal die KI über diesen Datenwust laufen und dann wird die gute Muster erkennen und wird mir sagen, was funktioniert. Das ist aber nicht so. Ich brauche schon gute Daten, ich muss die Daten gut organisieren und gut verstehen, damit meine KI wirklich etwas Sinnvolles berechnen kann. Es reichen eben nicht irgendwelche Daten, sondern die Daten müssen auch eine hohe Qualität haben, da sie sich sonst nicht integrieren und damit auch nicht interpretieren lassen. Dennoch arbeiten wir auch mit der Vision “Data Science” daran, immer mehr zu demokratisieren, d.h. es möglichst vielen Forschern zu ermöglichen, die Daten selbst auszuwerten, oder eben gewisse Prozessschritte in der Forschung durch KI zu ersetzen. Auch hierbei ist es wichtig, genau zu verstehen, was in welchem Bereich möglich ist. Und wieder denke ich, dass die richtige Erfassung/Qualität der Daten auch hier das A und O ist und dennoch oft unterschätzt wird.

Data Science Blog: Welches Wissen und welche Erfahrung setzen Sie für Ihre Data Scientists voraus? Und nach welchen Kriterien stellen Sie Data Science Teams für Ihre Projekte zusammen?

Generell sucht Roche als Healthcare-Unternehmen Bewerber mit einem Hintergrund in Informatik und Life Sciences zum Beispiel über ein Nebenfach oder einen Studiengang wie Biotechnologie oder Bioinformatik. Das ist deswegen wichtig, weil man bei Roche in allen Projekten mit Medizinern, Biologen oder Chemikern zusammenarbeitet, deren Sprache und Prozesse man verstehen sollte. Immer wichtiger werden zudem Experten für Big Data, Datenanalyse, Machine Learning, Robotics, Automatisierung und Digitalisierung.

Data Science Blog: Für alle Studenten, die demnächst ihren Bachelor, beispielsweise in Informatik, Mathematik oder auch der Biologie, abgeschlossen haben, was würden sie diesen jungen Damen und Herren raten, wie sie einen guten Einstieg ins Data Science bewältigen können?

Generell empfehle ich jungen Absolventen herauszufinden für welchen Bereich ihr Herz schlägt: Interessiere ich mich dafür, tief in die Biologie einzusteigen und grundlegende Prozesse zu verstehen? Möchte ich nahe am Patienten sei? Ooder ist mir wichtiger, dass ich auf möglichst große Datenmengen zugreifen kann?  Je nachdem, kann ich als Einstieg durchaus Traineeprogramme empfehlen, die es ermöglichen, in mehrere Abteilungen einer Firma Einblicke zu bekommen, oder würde eher eine Promotion empfehlen. Ich denke, das lässt sich eben nicht pauschalisieren. Für die Arbeit bei Roche ist sicherlich entscheidend, dass ich mich neben der Informatik/Data Science auch für das Thema Medizin und Biologie interessiere. Nur dann kann ich in den interdisziplinären Teams einen wertvollen Beitrag leisten und gleichzeitig auch meiner Leidenschaft folgen. Ich denke, dass das auch in anderen Branchen ähnlich ist.

Top 7 MBA Programs to Target for Business Analytics

Business Analytics refers to the science of collecting, analysing, sorting, processing and compiling various available data pertaining to different areas and facets of business. It also includes studying and scrutinising the information for useful and deep insights into the functioning of a business which can be used smartly for making important business-related decisions and changes to the existing system of operations. This is especially helpful in identifying all loopholes and correcting them.

The job of a business analyst is spread across every domain and industry. It is one of the highest paying jobs in the present world due to the sheer shortage of people with great analytical minds and abilities. According to a report published by Ernst & Young in 2019, there is a 50% rise in how firms and enterprises use analytics to drive decision making at a broad level. Another reason behind the high demand is the fact that nowadays a huge amount of data is generated by all companies, large or small and it usually requires a big team of analysts to reach any successful conclusion. Also, the nature and high importance of the role compels every organisation and firm to look for highly qualified and educated professionals whose prestigious degrees usually speak for them.

An MBA in Business Analytics, which happens to be a branch of Business Intelligence, also prepares one for a successful career as a management, data or market research analyst among many others. Below, we list the top 7 graduate school programs in Business Analytics in the world that would make any candidate ideal for this high paying job.

Data Scientist: Rock the Tech World

It’s almost 2020! Are you a data Rockstar or a laggard?

IDC agrees to the fact that the global data, 33 zettabytes in 2018 is predicted to grow to 175 zettabytes by 2025. That’s like ten times bigger the amount of data seen in 2017.

Isn’t this an exciting analysis?

Hold on! Are all the industries set for a digitally transformed future?

A digital transformed future is an opportunity of historic proportions. The way data is consumed today changes the way we work, live, and play. Businesses across the globe are now using data to transform themselves to adapt to these changes, become agile, improve customer experience, and to introduce new business models.

With the full dependency on online channels, connectivity with friends and family around the world has increased the consumption of data. Today, the entire economy is reliant on data. Without data, you’re lost.

Leverage the benefits of the data era

At the outset, with not many big data industries to be found, we can still agree to the fact that the knowledge for data skills is still early for professionals in the big data realm.

• Big data assisting the humanitarian aid
• Case study: During a disaster

Be it natural or conflict-driven – if the response is driven quickly, it minimizes problems that are predicted to happen. In such instances, big data could be of great help in helping improve the responses of the aid organizations.

Data scientists can easily use analytics and algorithms to provide actionable insights that can be used during emergencies to identify patterns in the data that is generated by online connected devices or from other related sources.

During a 2015 refugee crisis in Germany, the Sweden Migration Board saw 10,000 asylum seekers every week up from 2,500 asylum seekers they saw in a month. A critical situation where other organizations could have faced challenges in dealing with the problem. However, with the help of big data this agency could cope up with the challenges. The challenges were addressed by ensuring extra staff was hired and of securing housing started early. Big data was of aid to this agency, meaning since they were users of this the preprocessing technology for quite a long time, the predictions were given well ahead of time.

Earlier the results were not easy to extract due to obstruction such as not finding the relevant data. However, now with the launch of open data initiatives, the process has become easy.

• Tapping into talents of data scientist

The Defence Science and Technology Laboratory (Dstl) along with other government partners launched “The Data Science Challenge.” This is done to harness the skills of data science professionals, to check their capability of tackling real-world problems people face daily.

The challenge is part of a wider program set out majorly in the Defence Innovation Initiative.

It is an open data science challenge that welcome entrants from all facets of background and specialization to demonstrate their skills. The challenge is to acknowledge that the best of minds need not necessarily be the ones that work for you.

• The challenge comprises of two competitions each offering an award of £40,000
1. First competition – this analyzes the ability to analyze data that is in documents i.e. media reports. This helps the data scientist have a deeper understanding of a political situation like it occurs for those on the ground level and even for those assisting it from afar.
2. Second competition – the second test involves creating possible ways to detect and classify vehicles like buses, cars, and motorbikes easily from aerial imagery. A solution to be used for aiding the safe journey of vehicles going through conflict zones.

What makes the data world significant?

In all aspects, the upshot of the paradigm shift is that data has become a critical influencer in businesses as well as our lives. Internet of things (IoT) and embedded devices are already pacing their way in boosting the big data world.

Some great key findings based on research by IDC: –

• 75% of the population that interacts with data is estimated to stay connected by 2025.
• The number of embedded devices that can be found on driverless cars, manufacturing floors, and smart buildings is estimated to grow from less than one per person to more than four in the next decade.
• In 2025, the amount of real-time data created in the data sphere is estimated to be over 25% while IoT real-time data will be more than 95%.

With the data science industry becoming the top-end of the pyramid, a certified data scientist plays an imperative role today.

In recent times, it is seen that big data has emerged to be the célèbre in the tech industry, generating several job opportunities.

What do you consider yourself to be today?

Defining a data scientist is tough and finding one is tougher!

The importance of being Data Scientist

The incredible results of Machine Learning and Artificial Intelligence, Deep Learning in particular, could give the impression that Data Scientist are like magician. Just think of it. Recognising faces of people, translating from one language to another, diagnosing diseases from images, computing which product should be shown for us next to buy and so on from numbers only. Numbers which existed for centuries. What a perfect illusion. But it is only an illusion, as Data Scientist existed as well for centuries. However, there is a difference between the one from today compared to the one from the past: evolution.

The main activity of Data Scientist is to work with information also called data. Records of data are as old as mankind, but only within the 16 century did it include also numeric forms — as numbers started to gain more and more ground developing their own symbols. Numerical data, from a given phenomenon — being an experiment or the counts of sheep sold by week over the year –, was from early on saved in tabular form. Such a way to record data is interlinked with the supposition that information can be extracted from it, that knowledge — in form of functions — is hidden and awaits to be discovered. Collecting data and determining the function best fitting them let scientist to new insight into the law of nature right away: Galileo’s velocity law, Kepler’s planetary law, Newton theory of gravity etc.

Such incredible results where not possible without the data. In the past, one was able to collect data only as a scientist, an academic. In many instances, one needed to perform the experiment by himself. Gathering data was tiresome and very time consuming. No sensor which automatically measures the temperature or humidity, no computer on which all the data are written with the corresponding time stamp and are immediately available to be analysed. No, everything was performed manually: from the collection of the data to the tiresome computation.

More then that. Just think of Michael Faraday and Hermann Hertz and there experiments. Such endeavour where what we will call today an one-man-show. Both of them developed parts of the needed physics and tools, detailed the needed experiment settings, conducting the experiment and collect the data and, finally, computing the results. The same is true for many other experiments of their time. In biology Charles Darwin makes its case regarding evolution from the data collected in his expeditions on board of the Beagle over a period of 5 years, or Gregor Mendel which carry out a study of pea regarding the inherence of traits. In physics Blaise Pascal used the barometer to determine the atmospheric pressure or in chemistry Antoine Lavoisier discovers from many reaction in closed container that the total mass does not change over time. In that age, one person was enough to perform everything and was the reason why the last part, of a data scientist, could not be thought of without the rest. It was inseparable from the rest of the phenomenon.

With the advance of technology, theory and experimental tools was a specialisation gradually inescapable. As the experiments grow more and more complex, the background and condition in which the experiments were performed grow more and more complex. Newton managed to make first observation on light with a simple prism, but observing the line and bands from the light of the sun more than a century and half later by Joseph von Fraunhofer was a different matter. The small improvements over the centuries culminated in experiments like CERN or the Human Genome Project which would be impossible to be carried out by one person alone. Not only was it necessary to assign a different person with special skills for a separate task or subtask, but entire teams. CERN employs today around 17 500 people. Only in such a line of specialisation can one concentrate only on one task alone. Thus, some will have just the knowledge about the theory, some just of the tools of the experiment, other just how to collect the data and, again, some other just how to analyse best the recorded data.

If there is a specialisation regarding every part of the experiment, what makes Data Scientist so special? It is impossible to validate a theory, deciding which market strategy is best without the work of the Data Scientist. It is the reason why one starts today recording data in the first place. Not only the size of the experiment has grown in the past centuries, but also the size of the data. Gauss manage to determine the orbit of Ceres with less than 20 measurements, whereas the new picture about the black hole took 5 petabytes of recorded data. To put this in perspective, 1.5 petabytes corresponds to 33 billion photos or 66.5 years of HD-TV videos. If one includes also the time to eat and sleep, than 5 petabytes would be enough for a life time.

For Faraday and Hertz, and all the other scientist of their time, the goal was to find some relationship in the scarce data they painstakingly recorded. Due to time limitations, no special skills could be developed regarding only the part of analysing data. Not only are Data Scientist better equipped as the scientist of the past in analysing data, but they managed to develop new methods like Deep Learning, which have no mathematical foundation yet in spate of their success. Data Scientist developed over the centuries to the seldom branch of science which bring together what the scientific specialisation was forced to split.

What was impossible to conceive in the 19 century, became more and more a reality at the end of the 20 century and developed to a stand alone discipline at the beginning of the 21 century. Such a development is not only natural, but also the ground for the development of A.I. in general. The mathematical tools needed for such an endeavour where already developed by the half of the 20 century in the period when computing power was scars. Although the mathematical methods were present for everyone, to understand them and learn how to apply them developed quite differently within every individual field in which Machine Learning/A.I. was applied. The way the same method would be applied by a physicist, a chemist, a biologist or an economist would differ so radical, that different words emerged which lead to different langues for similar algorithms. Even today, when Data Science has became a independent branch, two different Data Scientists from different application background could find it difficult to understand each other only from a language point of view. The moment they look at the methods and code the differences will slowly melt away.

Finding a universal language for Data Science is one of the next important steps in the development of A.I. Then it would be possible for a Data Scientist to successfully finish a project in industry, turn to a new one in physics, then biology and returning to industry without much need to learn special new languages in order to be able to perform each tasks. It would be possible to concentrate on that what a Data Scientist does best: find the best algorithm. In other words, a Data Scientist could resolve problems independent of the background the problem was stated.

This is the most important aspect that distinguish the Data Scientist. A mathematician is limited to solve problems in mathematics alone, a physicist is able to solve problems only in physics, a biologist problems only in biology. With a unique language regarding the methods and strategies to solve Machine Learning/A.I. problems, a Data Scientist can solve a problem independent of the field. Specialisation put different branches of science at drift from each other, but it is the evolution of the role of the Data Scientist to synthesize from all of them and find the quintessence in a language which transpire beyond all the field of science. The emerging language of Data Science is a new building block, a new mathematical language of nature.

Although such a perspective does not yet exists, the principal component of Machine Learning/A.I. already have such proprieties partially in form of data. Because predicting for example the numbers of eggs sold by a company or the numbers of patients which developed immune bacteria to a specific antibiotic in all hospital in a country can be performed by the same prediction method. The data do not carry any information about the entities which are being predicted. It does not matter anymore if the data are from Faraday’s experiment, CERN of Human Genome. The same data set and its corresponding prediction could stand literary for anything. Thus, the result of the prediction — what we would call for a human being intuition and/or estimation — would be independent of the domain, the area of knowledge it originated.

It also lies at the very heart of A.I., the dream of researcher to create self acting entities, that is machines with consciousness. This implies that the algorithms must be able to determine which task, model is relevant at a given moment. It would be to cumbersome to have a model for every task and and every field and then try to connect them all in one. The independence of scientific language, like of data, is thus a mandatory step. It also means that developing A.I. is not only connected to develop a new consciousness, but, and most important, to the development of our one.

3. Hands-on experience: There’s a vast difference in theory and practical knowledge. One needs to familiarize themselves with the latest tools and technologies used by the industry. This is possible only if the individual is willing to work on projects and build things from scratch.

Despite all the promises, AI does prove to be a threat to job holders, if they don’t upskill or reskill themselves. The upcoming AI revolution will definitely disrupt the way we work, however, it will leave room for humans to perform more creative jobs in the future corporate world.

So a word of advice is to be prepared and stay future ready.

The Data Scientist Job and the Future

A dramatic upswing of data science jobs facilitating the rise of data science professionals to encounter the supply-demand gap.

By 2024, a shortage of 250,000 data scientists is predicted in the United States alone. Data scientists have emerged as one of the hottest careers in the data world today. With digitization on the rise, IoT and cognitive technologies have generated a large number of data sets, thus, making it difficult for an organization to unlock the value of these data.

With the constant rise in data science, those fail to upgrade their skill set may be putting themselves at a competitive disadvantage. No doubt data science is still deemed as one of the best job titles today, but the battles for expert professionals in this field is fierce.

The hiring market for a data science professional has gone into overdrive making the competition even tougher. New online institutions have come up with credible certification programs for professionals to get skilled. Not to forget, organizations are in a hunt to hire candidates with data science and big data analytics skills, as these are the top skills that are going around in the market today. In addition to this, it is also said that typically it takes around 45 days for these job roles to be filled, which is five days longer than the average U.S. market.

Data science

One might come across several definitions for data science, however, a simple definition states that it is an accumulation of data, which is arranged and analyzed in a manner that will have an effect on businesses. According to Google, a data scientist is one who has the ability to analyze and interpret complex data, being able to make use of the statistic of a website and assist in business decision making. Also, one needs to be able to choose and build appropriate algorithms and predictive models that will help analyze data in a viable manner to uncover positive insights from it.

A data scientist job is now a buzzworthy career in the IT industry. It has driven a wider workforce to get skilled in this job role, as most organizations are becoming data-driven. It’s pretty obnoxious being a data professional will widen job opportunities and offer more chances of getting lucrative salary packages today. Similarly, let us look at a few points that define the future of data science to be bright.

• Data science is still an evolving technology

A career without upskilling often remains redundant. To stay relevant in the industry, it is crucial that professionals get themselves upgraded in the latest technologies. Data science evolves to have an abundance of job opportunities in the coming decade. Since, the supply is low, it is a good call for professionals looking to get skilled in this field.

• Organizations are still facing a challenge using data that is generated

Research by 2018 Data Security Confidence from Gemalto estimated that 65% of the organizations could not analyze or categorized the data they had stored. However, 89% said they could easily analyze the information prior they have a competitive edge. Being a data science professional, one can help organizations make progress with the data that is being gathered to draw positive insights.

• In-demand skill-set

Most of the data scientists possess to have the in-demand skill set required by the current industry today.
