In this MP, you will implement the PLSA algorithm discussed in lectures 9.7 and 9.8 of the Text Mining Coursera course. You are not required to implement the PLSA algorithm with a background model (we ...

The original PLSA model does not contain a background model, which means set λ B to zero. The main data structures involved in the implementation of this EM algorithm are three matrices: T (topics by ...

Due to the vast growth of data collections, the statistical document modeling has become increasingly important in language processing areas. Probabilistic latent semantic analysis (PLSA) is a popular ...
