RandomForestClassifier Classifier Local

The RandomForestClassifier algorithm uses the scikit-learn RandomForestClassifier estimator to fit a model to predict the value of categorical fields.

For descriptions of the n_estimators, max_depth, criterion, random_state, max_features, min_samples_split, and max_leaf_nodes parameters, see the scikit-learn documentation at http://scikit-learn.org/stable/modules/generated/sklearn.ensemble.RandomForestClassifier.html.

Syntax

fit RandomForestClassifier <field_to_predict> from <explanatory_fields> [into <model name>]
[n_estimators=<int>] [max_depth=<int>] [criterion=<gini | entropy>] [random_state=<int>]
[max_features=<str>] [min_samples_split=<int>] [max_leaf_nodes=<int>]

You can save RandomForestClassifier models using the into keyword and apply new data later using the apply command.

... | apply sla_model

You can list the features that were used to fit the model, as well as their relative importance or influence with the summary command.

... | summary sla_model

Example

The following example uses RandomForestClassifier on a test set.

... | fit RandomForestClassifier SLA_violation from * into sla_model | ...
