Feature-NLP(32)

 

基础算法：

Frequent itemset mining

Collaborative filtering

LSA - SVD decomposition of text matrix.

NMF - constraint SVD

pLSA - probabilistic version of LSA (来新数据就傻眼了)

LDA - smoothed pLSA (可实时，加了prior)

GaP - A re-modeling of LDA

RBM - A re-modeling of LDA (dnn)

HDP - extending LDA to infinite (#semantics, 不用预先制定语义个数，好比”中餐馆模型“)
