Machine learning methods for clinical data analysis

Machine learning has become a powerful tool to mine for patterns in biological and clinical data, disease diagnosis, assist drug discovery and predict treatment outcomes. In collaboration with a wide range of clinical partners, we have analyzed and processed heterogeneous clinical data (images, laboratory results, medical records, etc.) and implemented supervised and unsupervised machine learning methods to improve clinical decision making or biomarker discovery. 

As a recent example, we have worked on a large cohort of chronically infected Hepatitis B patients treated with different antiviral treatments to identify new biomarkers of virological relapse after treatment discontinuation. The data set available for this patient cohort consists of different time-resolved measurements of 47 cytokines during treatment. We developed a supervised machine learning method that allowed for the first time to reveal the predictive potential of cytokines for Hepatitis B virological relapse. We identified a small subset of five cytokines able to predict relapse with a high accuracy at any time during treatment. This facilitates clinical decisions on the management of Hepatitis B patients, potentiality avoiding over or under-treatment .
