h2o (version 3.40.0.4)

h2o.predict_rules: Evaluates validity of the given rules on the given data. Returns a frame with a column per each input rule id, representing a flag whether given rule is applied to the observation or not.

Description

Evaluates validity of the given rules on the given data. Returns a frame with a column per each input rule id, representing a flag whether given rule is applied to the observation or not.

Usage

h2o.predict_rules(model, frame, rule_ids)

Arguments

model

A trained rulefit model.

frame

A frame on which rule validity is to be evaluated

rule_ids

Rule ids to be evaluated against the frame
