SEMINARI DI INFORMATICA

Mercoledì 23 Ottobre 2013 alle ore 17:30 in aula 1BC50, Paulo Lisboa (Liverpool John Moores University and St. Helens and Knowsley Teaching Hospitals) terrà un seminario dal titolo "Accuracy is not enough - a theoretical and practical tour of machine learning for medical decision support".

Abstract
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.
