Host: Dr. Peter Tino

Computer-based decision support in clinical medicine is likely to grow in importance as the 4P agenda develops (predictive, preventive, personalised, participatory healthcare). In practical terms, this involves complex non-linear data, combinations of different modalities, high-dimensionality and potentially also integration into clinical reasoning. Each of these aspects has implications for data-based modelling. In parallel, advances in machine learning have generated a plethora of high performing models, very few of which are ever used in the clinical setting. This talk will show why model evaluation necessarily involves more than performance accuracy or even ROC characteristics; explore some implications for model design; and discuss resulting theoretical developments related to information theory.

Biography: Paulo Lisboa is Professor in Industrial Mathematics in the School of Computing and Mathematical Sciences at Liverpool John Moores University and Research Professor at St Helens & Knowsley Teaching Hospitals. His research is focused on computer-based decision support in healthcare and data analytics in public health, sports science and computational marketing. In particular he has an interest in principled approaches to interpretable modelling of non-linear data and processes.

He has over 250 refereed publications with awards for citations. He chairs the Medical Data Analysis Task Force in the Data Mining Technical Committee of the IEEE -CIS and is Associate Editor for IET Science Measurement and Technology, Neural Computing Applications, Applied Soft Computing and Source Code for Biology and Medicine. He is also a member of the EPSRC Peer Review College and an expert evaluator for the European Community DG-INFSO.
