DOC Note shape of binary binarized output
Rebased, Implemented test for sparse_output in MultilabelBinarizer
Improved test coverage for label.py by editing exisitng testing functions
Trivial chnage, Restarting travis joblib failure
Deprecated multilabel_ and indicator_matrix_, used calls to MultilableBinarizer to replace seq of seq handling
Updated documentation with sparse support
Revised test to look for warning in the list of warnings
Included test for ensuring deprcation warning is raised with seq of seq tests for LabelBinarizer
Handled case of row with all zeros to _inverse_binarize_multiclass by raising value error
Included authors entry
Removed redundant if statements in inverse_transform, revised line for detecting uniques other than 1 and 0, and changed deprecation warnings
Caught lb.multilabel_ warnings
Mkaing sure warnings are raised before checking type
suppresed most warnings
Included test to improve coverage, Removed unreachable condition in binary inverse transform
Corrected indentation on line 153
Finding the failing doctest with travis when type forcing is excluded
Commented on CSR matricies in the test examples specifiec at the begginging
