Plsi python
Probabilistic latent semantic analysis (PLSA), also known as probabilistic latent semantic indexing (PLSI, especially in information retrieval circles) is a statistical technique for the analysis of two-mode and co-occurrence data. In effect, one can derive a low-dimensional representation of the observed variables in terms of their affinity to certain hidden variables, just as in latent semantic analysis, from which PLSA evolved. WebLSA (Latent Semantic Analysis) also known as LSI (Latent Semantic Index) LSA uses bag of word (BoW) model, which results in a term-document matrix (occurrence of terms in a …
