Feature Importance per Class

[EasonSun]

Hi Ando,

Thank you for this wonderful work. I found this should be able to generate feature importance for each class? I can do prediction, bias, contributions = ti.predict(rf, instance) for each instance and average the contributions for each feature. Is this the right thing to do?

If this word really can generate feature importance for each class, then I suggest to add this point to the readme because it took me a while to search. I am also wondering why feature importance per class is not a popular topic for rf, at least on Google. Is that because rf is not at this job?

Thank you
