Sticky HDP-HMM for time series denoising

Suppose that we observed several time series and their underlying processes are discreted-valued. The sticky hidden-Markov model can be used to denoised these noisy time series. Run python3 shdp_demo.py to show a demonstration (with animation, see demo on Youtube).
