Knowledge Discovery of Multiple-topic Document using Parametric Mixture Model with Dirichlet Prior
Published on Feb 4, 20253657 Views
Documents, such as those seen onWikipedia and Folksonomy, have tended to be assigned with multiple topics as a meta-data. Therefore, it is more and more important to analyze a relationship between a d
