Convergence indicator? #6

Closed usptact closed 8 years ago

usptact commented 8 years ago

When learning a model, is there any indicator of convergence available or easy to compute? Currently the only information is the iteration number.

Thanks for your suggestion. Typically, we training a topic model with about 500 iterations, which usually get good results. A better way is to output perplexity to illustrate the convergence more clearly.

I'm sorry that the code has not maintained for a while after my graduation. As I found there are still so many people interest in BTM, I'm plan to develop a next version of it in few months, which will bring much improvements includes the convergence tracking.
