An Optimal Policy for Patient Laboratory Tests in Intensive Care Units

no code implementations14 Aug 2018 Li-Fang Cheng, Niranjani Prasad, Barbara E. Engelhardt

There exists an inherent trade-off in the selection and timing of lab tests between considerations of the expected utility in clinical decision-making of a given test at a specific time, and the associated cost or risk it poses to the patient.

Large Linear Multi-output Gaussian Process Learning

1 code implementation30 May 2017 Vladimir Feinberg, Li-Fang Cheng, Kai Li, Barbara E. Engelhardt

Gaussian processes (GPs), or distributions over arbitrary functions in a continuous domain, can be generalized to the multi-output case: a linear model of coregionalization (LMC) is one approach.

A Reinforcement Learning Approach to Weaning of Mechanical Ventilation in Intensive Care Units

no code implementations20 Apr 2017 Niranjani Prasad, Li-Fang Cheng, Corey Chivers, Michael Draugelis, Barbara E. Engelhardt

The management of invasive mechanical ventilation, and the regulation of sedation and analgesia during ventilation, constitutes a major part of the care of patients admitted to intensive care units.

Sparse Multi-Output Gaussian Processes for Medical Time Series Prediction

1 code implementation27 Mar 2017 Li-Fang Cheng, Gregory Darnell, Bianca Dumitrascu, Corey Chivers, Michael E Draugelis, Kai Li, Barbara E. Engelhardt

In the scenario of real-time monitoring of hospital patients, high-quality inference of patients' health status using all information available from clinical covariates and lab tests is essential to enable successful medical interventions and improve patient outcomes.
