LDA的c语言实现，LDA是一个针对文档的分层概率模型。,This is a C implementation of latent Dirichlet allocation (LDA), a model of discrete data . LDA is a hierarchical probabilistic model of documents.

This code implements hierarchical LDA with a fixed depth tree and a stick breaking prior on the depth weights. An infinite-depth tree can be approximated by setting the depth to be very high. This code requires that you have installed the GSL p
