Discriminative Switching Linear Dynamical Systems applied to Physiological Condition Monitoring

Konstantinos Georgatzis,
Christopher K. I. Williams

Abstract: We present a Discriminative Switching Linear Dynamical System (DSLDS) applied to patient monitoring in Intensive Care Units (ICUs). Our approach is based on identifying the state-of-health of a patient given their observed vital signs using a discriminative classifier, and then inferring their underlying physiological values conditioned on this status. The work builds on the Factorial Switching Linear Dynamical System (FSLDS) (Quinn et al., 2009) which has been previously used in a similar setting. The FSLDS i… Show more
