Insights from Negative Results

Session Organizer: Karol Desnos (IETR, France) and Shuvra Bhattacharyya (University of Maryland, College Park , USA & IETR, France)

Motivation: Frequently, researchers choose to develop an idea because early or theoretical results seem promising. When scaling up, or when implementing the idea in a realistic scenario, the results are not as good as expected. Unfortunately, publishing such results is very difficult, because the reviewing process generally promotes positive results. When such a scenario occurs, scientists sometimes try to publish the idea anyway, by "disguising" the results in a positive way: by deliberately overlooking negative aspects of their results or by choosing an unusual evaluation metric.

Session objective:: The special session is dedicated to the presentation of ideas that lead to negative results. Contributions are expected to present the original idea, to explain why this idea was expected to provide good results, to present how and why it failed, and to discuss the presence (or absence) of solutions to solve encountered issues.


The objectives of this special session are fourfold:

  • To give credit to the research process that lead to the negative result.

  • To avoid disguising a negative result into a good one, which may trick other researchers into implementing an idea only to realize its actual negative side-effects later.

  • To help prevent other researchers from trying to develop this idea. If the idea seemed good at first, other researcher may have it one day. By publishing the idea and its unexpected negative results, you may save some time for other researchers.

  • To promote good ideas behind the negative results. Some ideas producing negative results may need some adapting or fine tuning before they can achieve their potential. A negative results forum provides a way to disseminate these kinds of ideas so they don't just get buried.

Previous edition:: This is the third edition of a SAMOS special session devoted to interesting negative results. The first edition was part of SAMOS 2018. As examples of previous papers under this theme, two selected papers from the first edition can be found at the following links:

European Projects on Embedded and High Performance Computing for Health Applications

Session Organizer: Giovanni Agosta (POLIMI, Italy)

Abstract: The rise of IoT systems, coupled with the availability of large scale computational resources accessible to a wider range of industrial and research actors is leading to the emergence of new application scenarios such as biomedical machine learning and in silico drug design. As a result, several collaborative research projects have brought together computer science and electronics teams to cooperate with bioengineers and health specialists. This special sessions reports recent results from such projects, focusing on the advances in high performance and embedded computing that enable this class of applications.
