Python Implementation of "Latent Dirichlet Allocation, David, Blei, 2003"

Topics on NIPS 2014(only abstracts) are modeled. Please refer to example.py

• Estimation algorithm implementation

• Inference algorithm implementation
• The smoothing factor for the topic word parameter \beta

It's still unknown whether the estimation implementation is correct or not, though tests have been written and the increase of lower bound can be seen during training.
