Spike-and-Slab Dirichlet Process Mixture Models
In this paper, Spike-and-Slab Dirichlet Process (SS-DP) priors are introduced and discussed for non-parametric Bayesian modeling and inference, especially in the mixture models context. Specifying a spike-and-slab base measure for DP priors combines the merits of Dirichlet process and spike-and-slab priors and serves as a flexible approach in Bayesian model selection and averaging. Computationa...
متن کاملSpike Sorting Using Time-Varying Dirichlet Process Mixture Models
Spike sorting is the task of grouping action potentials observed in extracellular electrophysiological recordings by source neuron. In this thesis a new incremental spike sorting model is proposed that accounts for action potential waveform drift over time, automatically eliminates refractory period violations, and can handle “appearance” and “disappearance” of neurons during the course of the ...
متن کاملEstimating Mixture of Dirichlet Process Models
Current Gibbs sampling schemes in mixture of Dirichlet process (MDP) models are restricted to using \conjugate" base measures which allow analytic evaluation of the transition probabilities when resampling con gurations, or alternatively need to rely on approximate numeric evaluations of some transition probabilities. Implementation of Gibbs sampling in more general MDP models is an open and im...
متن کاملTime-sensitive Dirichlet process mixture models
We introduce Time-Sensitive Dirichlet Process Mixture models for clustering. The models allow infinite mixture components just like standard Dirichlet process mixture models. However they also have the ability to model time correlations between instances. Research supported in part by NSF grants NSF-CCR 0122481, NSF-IIS 0312814, and NSFIIS 0427206.

متن کاملDistributed Inference for Dirichlet Process Mixture Models
Bayesian nonparametric mixture models based on the Dirichlet process (DP) have been widely used for solving problems like clustering, density estimation and topic modelling. These models make weak assumptions about the underlying process that generated the observed data. Thus, when more data are collected, the complexity of these models can change accordingly. These theoretical properties often...
