Could you please update the parameters list to include a description of the noise parameter.

I can't see where self.noise gets updated to the noise value set in the mimic function.

This feature lets users add noise to mimic.
Users can add an optional "noise" argument to set the noise between 0.00 ~ 0.10, which corresponds to 0 to 10% noise. (Which gets renormalized). The default is set to 0.
0.01 corresponds to adding 1% probability to all probabilities and conditional probabilities to the features and then renormalizing them.
Adopted from 4.3 Refining Samples Generated by MIMIC in Randomized Local Search as Successive Estimation of Probability Densities by Charles L. Isbell, Jr.
