Seminar on Applied and Industrial Mathematics
- 9 May 2022, 18:30–20:30 Speaker: Ioannis Tsamardinos (U. Creta and JADBio) Title: Automated Machine Learning for Knowledge Discovery and Predictive Modeling Abstract: Automated Machine Learning (AutoML) is a rising subfield of Machine Learning and Artificial Intelligence. It promises to democratize ML to non-experts, boost productivity, and reduce analysis methodological errors. The goal of AutoML is to create a predictive model for an outcome of interest optimizing the choice of the algorithms in the machine learning pipeline and their hyper-parameter values. More than that, however, it is also to offer all visualizations, interpretations, and explanations a human expert would put the model into production and make it operational. In this talk, we'll describe the problem of AutoML and offer some scientific and engineering solutions for each subproblem. These are implemented into the JADBio system, short for Just Add Data Bio. JADBio is the only AutoML system specifically designed with knowledge discovery in mind, especially for high-dimensional, low-sample datasets. Knowledge discovery is provided in the form of feature selection, i.e., the minimal-size subset of features that leads to an optimally predictive model. Case study examples will be presented. Bio: Ioannis Tsamardinos, Ph.D., is a Professor at the Computer Science Department of the University of Crete, CEO and co-founder of JADBio, a University start-up. He obtained his Ph.D. from the Intelligent Systems Program at the University of Pittsburgh in 2001. He then worked as Assistant Professor at the Department of Biomedical Informatics at Vanderbilt University until 2006, when he returned to Greece. Prof. Tsamardinos’ main research directions include machine learning, bioinformatics, and artificial intelligence. More specifically, his work emphasizes automated machine learning, feature selection, and causal discovery. Prof. Tsamardinos has over 140 publications in international journals, conferences, and books. Distinctions include Gold Medal in the Student Paper Competition in MEDINFO 2004, the Outstanding Student Paper Award in AIPS 2000, the NASA Group Achievement Award for participation in the Remote Agent team, and others. Statistics on recognition of work include more than 10000 citations (1000+ a year) and an h-index of 41 (as estimated by Google Scholar). Ioannis has been awarded the European and Greek national grants of excellence, the ERC Consolidator, ERC PoC, and the ARISTEIA II grants, respectively.
