On the Integration of Topic Modeling and Dictionary Learning
Lingbo Li, Mingyuan Zhou, Guillermo Sapiro, Lawrence Carin · 2011
A new nonparametric Bayesian model is developed to integrate dictionary learning and topic model into a unified framework. The model is employed to analyze partially annotated images, with the dictionary learning performed directly on image patches. Efficient inference is performed with a Gibbsslice sampler, and encouraging results are reported on widely used datasets. 1.
