Variational Bayesian Inference For A Scale Mixture Of Normal Distributions Handling Missing Data

2017-11-22 · G. Revillon, A. Djafari, C. Enderli

In this paper, a scale mixture of Normal distributions model is developed for classification and clustering of data having outliers and missing values. The classification method, based on a mixture model, focuses on the introduction of latent variables that gives us the possibility to handle sensitivity of model to outliers and to allow a less restrictive modelling of missing data. Inference is processed through a Variational Bayesian Approximation and a Bayesian treatment is adopted for model learning, supervised classification and clustering.

Streaming Variational Inference for Bayesian Nonparametric Mixture Models

2014-12-01 · Alex Tank, Nicholas J. Foti, Emily B. Fox

In theory, Bayesian nonparametric (BNP) models are well suited to streaming data scenarios due to their ability to adapt model complexity with the observed data. Unfortunately, such benefits have not been fully realized …
