Change-point detection in hierarchical circadian models

作者:

Highlights:

• Bayesian change-point detection on sequences of high-dimensional and heterogeneous observations with temporal structure.

• Heterogeneous-cirdadian mixture models with non-stationary and periodic covariance functions.

• Maximum-a-posteriori (MAP) detection from low-dimensional time-series of discrete latent variables.

• Applied experiments to human behavior modelling and detection of changes in mental health patients.
