Longitudinal Analysis with Self-Registration

The purpose of this study was to analyze sequences of images, i.e. movies, to examine the effect of neuromuscular electrical stimulation (NMES) in reducing the risk of developing pressure ulcers. An efficient procedure for mining spatial-temporal data (movies) was developed, called LASR (pronounced "laser").

HCP

Estimation of parameters in 3-segment (i.e. 2 change-point) regression models with heteroscedastic variances based on both likelihood and hybrid Bayesian approaches, with and without continuity constraints at the change points.

rNMF

Robust Non-negative matrix factorization (rNMF) is a modern method for obtaining low dimensional structure from high dimensional data. It allows both automatic and semi-supervised control to handle different types of corruptions.
