  1. How to Enable Multiple Classes Classification? If set all tags in 'positiveTags' or 'negativeTags'. Starting from index, tags will be encoded to 1,2,3,4,..

  2. Is Binning and Categorical Variable Support? EqualTotal and EqualInterval binnings are supported, while EqualPositive and EqualNegative are not supported. Categorical variable are not supported since categorical variable are computed as positive ratio in binary-classification.

  3. Only NN algorithm Supported for Multiple Classes Classification

  4. Eval Outputs are just Confusion Matrix
