Discrete PCA builds components for discrete data rather like PCA and ICA does for real data. The method has a long history and is most commonly used in genetics. Recent insights into the method are described here, and some examples of given of its use in automatically building a topic model for a document collection, and in its use as a tool for relevance estimation in search. The topic model can also be subsequently used in search. This discussion paper describes our ongoing research here.
