Get started with Topic Modeling using LDA with MALLET.MAchine Learning for LanguagE Toolkit, in short MALLET, is a tool written in Java for application of machine learning like natural language processing, document classification, clustering, topic modeling and information extraction to texts. In machine learning and natural language processing, a topic model is a type of statistical model for discovering the abstract "topics" that occur in a collection of documents. Topic modeling is a frequently used text-mining tool for discovery of hidden semantic structures in a text body.

Topic modeling the theme of this post deals with the problem of automatically classifying sets of documents into themes.The basic assumption behind LDA is that each of the documents in a collection consist of a mixture of collection-wide topics. Latent Dirichlet allocation (LDA) is cited as the simplest topic modelling method. No official implementation, but several implementations in different programing languages ( Java, Python, R I managed to implement LDA topic modeling but I still couldnt make it work for HDP.
