Regularized Sparse Gaussian Processes

no code implementations13 Oct 2019 Rui Meng, Herbert Lee, Soper Braden, Priyadip Ray

An issue faced by SGP, especially in latent variable models, is the inefficient learning of the inducing inputs, which leads to poor model prediction.

Facial Expression Recognition (FER) Gaussian Processes +3

Hierarchical Hidden Markov Jump Processes for Cancer Screening Modeling

no code implementations13 Oct 2019 Rui Meng, Soper Braden, Jan Nygard, Mari Nygrad, Herbert Lee

In this paper, we propose a piece-wise stationary transition matrix to explain the heterogeneity in time.

Nonstationary Multivariate Gaussian Processes for Electronic Health Records

no code implementations13 Oct 2019 Rui Meng, Braden Soper, Herbert Lee, Vincent X. Liu, John D. Greene, Priyadip Ray

We propose multivariate nonstationary Gaussian processes for jointly modeling multiple clinical variables, where the key parameters, length-scales, standard deviations and the correlations between the observed output, are all time dependent.
