Terrance Savitsky (202) 691-7382 Bayesian non-parametric inference focused on discovering sub-groups or sub-sets of the data with distinct behavioral profiles or high relevance. Methods include non-parametric prior formulations including dependent Dirichlet processes to discover sub-groups, anistropic Gaussian processes for non-linear functional data estimation, and factor analytic methods to uncover sparse latent constructs.
