LDA is a probabilistic topic model to discover the hidden thematic structure in large archives of documents. LDA-Col model is an extended model based on LDA model. In this paper, we introduced LDA-Col model in detail, including the plate notation, generative process and inference. Finally, we present experiment in topic words discovery to show the discovery performance differences between the LDA model and LDA-Col model. © 2015 SPIE. Source
