ENH NonBLASDotWarning -> EfficiencyWarning; Improve error message
DOC Add exceptions module to modules/classes.rst
MAINT Move ConvergenceWarning, UndefinedMetricWarning et al into exceptions
MAINT Remove ChangedBehaviorWarning from base
DOC/FIX Improve DataConversionWarning's docstring
Residues can be empty if the rank of X does not satisfy the
conditions described in scipy.linalg.lstsq documentation.
As residues are not that useful (i.e. we're not doing
stat testing), this property is deprecated and will be
removed in sklearn 0.19.
* Updated _check_solver_option to include sample_weight check
* Updated all calls to _check_solver_option()
* Updated documentation of class_weight throughout logistic.py
* Added sample_weight parameter to logistic_regression_path.
* Added handling of sample weights to logistic_regression_path.
* Added sample_weight parameter to _log_reg_scoring_path.
* Added handling of sample weights to _log_reg_scoring_path.
* Added sample_weight parameter to fit() in the LogisticRegression class.
* Added handling of sample sample weights in LogisticRegression.fit()
* Added sample_weight parameter to fit() in the LogisticRegressionCV class.
* Added handling of sample weights in LogisticRegressionCV.fit()
* Added test_logistic_regressioncv_sample_weights, which:
* tests that a ValueError is raised if liblinear is used with
sample weights
* tests that passing sample weights as np.ones(y.shape[0]) is
the same as not passing them (default None)
* tests that using both lbfgs and newton-cg solvers with
sample weights yields the same results
* tests that passing class weights to scale one class is the
same as passing sample weights for the training data of just
that class
* Fixed bug with *= in logistic_regression_path.
* Fixed bug in test_logistic_regressioncv_sample_weights where
no data was created prior to fitting.
* Changes to accepted sample_weight type.
* Fixed bug in naming of sample_weight when passed from
_log_reg_scoring_path to logistic_regression_path.
* Fixed issue of sample_weight=None being converted to np.array()
and then not being reconigzed as None.
* Added tests for LogisticRegression
* Attempting to fix same issue as 9d3becf by instead implementing
if statement in bagging.py.
* Added TODO to eliminate check for liblinear w/ sample weights
in bagging.py
