LDA (Latent Dirichlet Allocation)

This is a python implementation of LDA using gibbs sampling algorithm.

算法原理参考 ./book 下文件,其中 "LDA-by-Gibbs-samping.pdf" 是吉布斯采样在LDA中使用的详细推导

代码参考 ./src 下文件,完全按照 "Parameter estimation for text analysis" 一文第 20 页的 "Fig. 8. Gibbs sampling algorithm for latent Dirichlet allocation" 来实现的
