SVD non-convergence issue in NB regression #5

Closed thekingofkings closed 6 years ago

thekingofkings commented 6 years ago

NB_regression_evaluation does not converge on simple income_features

Temporary solution:

  1. Use Linear regression instead
  2. Convert naive income_features into summarized features, i.e. percentage, entropy
thekingofkings commented 6 years ago

Convert income_raw_features to summarized features

@wingsweihua implemented the feature conversions.
