16:00-16:05 Introduction & Overview on Responsible Data Science

Title: Better omics-based predictions through the use of big co-data

Abstract: In typical cancer genomics studies, the number of samples, n, is relatively small, say 50 to 500, compared to the number of features, p, say 10^3 to 10^6. Fortunately, a potentially large amount of prior information on the features may be available. Some examples of such ‘co-data’ are: p-values from an external study, additional molecular measurements or genomic annotation. The statistical challenge is to make responsible use of such co-data to potentially improve predictions and classifications for individuals.  We discuss Empirical Bayes as an approach to automatically and objectively include the co-data information in several prediction algorithms, such as penalized regression and the random forest. The emphasis will be on concepts, rather than on mathematical technicalities.  The systematic use of co-data can considerably improve predictions and feature selection, which we demonstrate with an application of the methodology to molecular cervical cancer diagnostics. Finally, some extensions to other problems, such as network estimation, are shortly discussed.

16:30-16:55 Speaker 2:  Melanie Peters, Director of the Rathenau Institute

Title: Society first, data second

Abstract: The possibilities of data are endless. Collecting, analyzing and combining data allows scientists to discover patterns in behavior or discourse that were hard to study before. Much is expected form these new possibilities. Especially in the area of health. However, what people do and write is not always what they need or what the collective needs. For marketeers this type of information may be enough, if the objective is stimulate buying and satisfy individual instant needs. For health professionals and those working in the public interest it is not what their task is about. It is about long term public health. Understanding the public interest and deciding which interventions in health are desired, requires deliberation, a back and forth discussion. This discussion can be informed by data, but not decided by data. How to design health research and health policy? And how to make use of data and empower patients and society?

The Rathenau Institute is a public think tank that informs politicians, decision makers and all of us about science and technology in order to make better informed choices. We do research and stimulate debate about the societal impact of new technologies, such as data. In the last year we published about data in the medical field (“Measurable man”: RATH_Meetbare Mens_DEF) and about the digital society and human rights (“Upgrade”: Opwaarderen_FINAL).

On 13 April, we will hold our monthly seminar series on Responsible Data Science (RDS), a joint collaboration of expert researchers from 11 knowledge institutions across the Netherlands: Academisch Medisch Centrum (AMC), Centrum Wiskunde en Informatica (CWI), Delft University of Technology (TUD), Eindhoven University of Technology (TU/e), Leiden University (LU), Leiden University Medical Center (LUMC), Radboud University Nijmegen (RU), Tilburg University (UvT), University of Amsterdam (UvA), VU Medical Center Amsterdam (VUmc), VU University Amsterdam.

The RDS initiative is driven by the omnipresence of data making society increasingly dependent on data science. Despite its great potential, there are also many concerns on irresponsible data use. Unfair or biased conclusions, disclosure of private information, and non-transparent data use, may inhibit future data science applications.

The RDS programme aims at generating scientific breakthroughs by making data science responsible by design. In RDS researchers from multiple disciplines connect to develop techniques, tools, and approaches to ensure fairness, accuracy, confidentiality, and transparency.

Big data is changing the way we do business, socialize, conduct research, and govern society. Data are collected on anything, at any time, and in any place. Organizations are investing heavily in Big data technologies and data science has emerged as a new scientific discipline providing techniques, methods, and tools to gain value and insights from new and existing data sets. Data abundance combined with powerful data science techniques has the potential to dramatically improve our lives by enabling new services and products, while improving their efficiency and quality. Many of today’s scientific discoveries (e.g., in health) are fuelled by developments in statistics, data mining, machine learning, databases, and visualization.
