F1 Score fix :

  • deals with classes yet without predictions, which result in zero division. Now it maches sklearn. Also makes a difference between macro and micro F1
  • pushes ROCAUC to BasicPerformanceEvaluator

Log loss :

  • Adds the log loss metric, and maches sklearn

evaluate prequential delayed regression

  • Add prequential delayed evaluation for regression
