Bugs fixed:
- Incorrect estimation of total RAM size on Windows and Mac OS, #989
- Failure when dataset is a
numpy.ndarray
withorder='F'
- Disable
boost_from_average
when baseline is specified
Improvements:
- Polymorphic raw features storage (2x---25x faster data preparation for numeric features in non-float32 columns as either
pandas.DataFrame
ornumpy.ndarray
withorder='F'
). - Support AUC metric for
CrossEntropy
loss on CPU - Added
datasets.rotten_tomatoes()
, a textual dataset - Usability of
monotone_constraints
, #950
Speedups:
- Optimized computation of
CrossEntropy
metric on CPUs with SSE3
