Towards this\, one can leverage the vast number of longitudinal signals---e.g.\, repeated heart rate\, res piratory rate\, blood cell counts\, creatinine measurements---that are alr eady recorded by clinicians to track an individual's health. Motivated by this problem\, we propose a reliable event prediction framework comprising two key innovations. First\, we extend existing state-of-the-art in joint -modeling to tackle settings with large-scale\, (potentially) correlated\, high-dimensional multivariate longitudinal data. For this\, we propose a flexible Bayesian nonparametric joint model along with scalable stochastic variational inference techniques for estimation. Second\, we use a decisi on-theoretic approach to derive an optimal detector that trades-off the co st of delaying correct adverse-event detections against making incorrect a ssessments. On a challenging clinical dataset on patients admitted to an I ntensive Care Unit\, we see significant gains in early event-detection per formance over state-of-the-art techniques. \n\nSEE PDF FOR MORE DETAILS\n DTSTART:20170207T203000Z DTEND:20170207T213000Z SUMMARY:SEMINAR: Scalable Joint Models for Reliable Event Prediction: Appli cation to Monitoring Adverse Events using Electronic Health Record Data URL:/epi-biostat-occh/channels/event/seminar-scalable- joint-models-reliable-event-prediction-application-monitoring-adverse-even ts-using-265517 END:VEVENT END:VCALENDAR
