- 33. Center for DataScience Paris-Saclay • We need data engineers and trainers to support research • ideally: 75% research scientists, 25% research engineers • We are lucky in France that the position exists in public research • Tasks • integrating research code into general-purpose professional software (e.g., scikit-learn,Torch) • providing an interface between computational infrastructure (e.g., clouds) and scientists • training scientists to use the tools 33 WHAT CNRS CAN DO
- 34. Center for DataScience Paris-Saclay34 WHAT CNRS CAN DO Incentives
- 35. Center for DataScience Paris-Saclay35 WHAT CNRS CAN DO Most data scientists, as other scientists, are trained and incentivized to do research on highly specialized domains. They search scientific visibility in their international community, which is equally highly specialized, because their carrier advancement is almost entirely based on peer-reviewed publications. Even when they would have the expertise, they have little incentive to venture into the tool builder (data engineer) role since software authorship has little value in their evaluation, and it can only serve them implicitly through the visibility they gain in the community of tool users. By the same token, they have little incentive to venture into domain sciences and to tackle economic or societal challenges. It is possible that a domain science or an industrial project requires new techniques which then can be published in data science venues, but this is not guaranteed at all. It usually takes heavy investment of time and effort to be able to understand domain problems, so excursions into domain sciences are highly risky. Even when such collaborations are established, the data scientist has a strong prior to use his/her favorite methodology which is not necessarily the best solution for a given problem. Finally, the data scientist has little incentive to bring the project to full fruition, and he/she often “runs away” with an abstract data science problem (and solution) extracted from the project. Symmetrically, domain scientist and industrial domain experts have no incentive to advance data science and to develop and publish new techniques, as long as their data science problems get solved. When they venture into tool development, they have little incentive in developing general purpose tools.

- 37. • Overweight (e.g,double count) out-of-domain papers in every evaluation • Make software tool ownership count Affirmative action 37 TAKE HOME MESSAGE NO2
- 38. Center for DataScience Paris-Saclay38 TAKE HOME MESSAGE NO3 Co-locality is important. It would be desirable that data science for scientific data in France be grouped into 5-6 sites of similar size. Resources and experience can and should be shared.
