eli5 0.6

0.6 (2017-05-03)

• Better scikit-learn Pipeline support in eli5.explain_weights: it is now possible to pass a Pipeline object directly. Curently only SelectorMixin-based transformers, FeatureUnion and transformers with get_feature_names are supported, but users can register other transformers; built-in list of supported transformers will be expanded in future. See sklearn-pipelines for more.

• Inverting of HashingVectorizer is now supported inside FeatureUnion via eli5.sklearn.unhashing.invert_hashing_and_fit. See sklearn-unhashing.

• Fixed compatibility with Jupyter Notebook >= 5.0.0.

• Fixed eli5.explain_weights for Lasso regression with a single feature and no intercept.

• Fixed unhashing support in Python 2.x.

• Documentation and testing improvements.

0.5 (2017-04-27)

• LightGBM support: eli5.explain_prediction and eli5.explain_weights are now supported for LGBMClassifier and LGBMRegressor (see eli5 LightGBM support <library-lightgbm>).

• fixed text formatting if all weights are zero;

• type checks now use latest mypy;

• testing setup improvements: Travis CI now uses Ubuntu 14.04.

0.4.2 (2017-03-03)

• bug fix: eli5 should remain importable if xgboost is available, but not installed correctly.

0.4.1 (2017-01-25)

• feature contribution calculation fixed for eli5.xgboost.explain_prediction_xgboost

0.4 (2017-01-20)

• eli5.explain_prediction: new ‘top_targets’ argument allows to display only predictions with highest or lowest scores;

• eli5.explain_weights allows to customize the way feature importances are computed for XGBClassifier and XGBRegressor using importance_type argument (see docs for the eli5 XGBoost support <library-xgboost>);

• eli5.explain_weights uses gain for XGBClassifier and XGBRegressor feature importances by default; this method is a better indication of what’s going, and it makes results more compatible with feature importances displayed for scikit-learn gradient boosting methods.

0.3.1 (2017-01-16)

• packaging fix: scikit-learn is added to install_requires in setup.py.

0.3 (2017-01-13)

• eli5.explain_prediction works for XGBClassifier, XGBRegressor from XGBoost and for ExtraTreesClassifier, ExtraTreesRegressor, GradientBoostingClassifier, GradientBoostingRegressor, RandomForestClassifier, RandomForestRegressor, DecisionTreeClassifier and DecisionTreeRegressor from scikit-learn. Explanation method is based on http://blog.datadive.net/interpreting-random-forests/ .

• eli5.explain_weights now supports tree-based regressors from scikit-learn: DecisionTreeRegressor, AdaBoostRegressor, GradientBoostingRegressor, RandomForestRegressor and ExtraTreesRegressor.

• eli5.explain_weights works for XGBRegressor;

• new TextExplainer <lime-tutorial> class allows to explain predictions of black-box text classification pipelines using LIME algorithm; many improvements in eli5.lime <eli5-lime>.

• better sklearn.pipeline.FeatureUnion support in eli5.explain_prediction;

• rendering performance is improved;

• a number of remaining feature importances is shown when the feature importance table is truncated;

• styling of feature importances tables is fixed;

• text-based formatting of decision trees is changed: for binary classification trees only a probability of “true” class is printed, not both probabilities as it was before.

• eli5.explain_weights supports feature_filter in addition to feature_re for filtering features, and eli5.explain_prediction now also supports both of these arguments;

• ‘Weight’ column is renamed to ‘Contribution’ in the output of eli5.explain_prediction;

• new show_feature_values=True formatter argument allows to display input feature values;

• fixed an issue with analyzer=’char_wb’ highlighting at the start of the text.

0.2 (2016-12-03)

• lightning support;

• eli5.show_weights and eli5.show_prediction functions;

• eli5.explain_weights and eli5.explain_prediction functions;

• eli5.lime <eli5-lime> improvements: samplers for non-text data, bug fixes, docs;

• HashingVectorizer is supported for regression tasks;

• performance improvements - feature names are lazy;

• sklearn ElasticNetCV and RidgeCV support;

• it is now possible to customize formatting output - show/hide sections, change layout;

• sklearn OneVsRestClassifier support;

0.0.6 (2016-10-12)

• Candidate features in eli5.sklearn.InvertableHashingVectorizer are ordered by their frequency, first candidate is always positive.

0.0.5 (2016-09-27)

• HashingVectorizer support in explain_prediction;

• add an option to pass coefficient scaling array; it is useful if you want to compare coefficients for features which scale or sign is different in the input;
