DataFrame.DecisionTree.Model
Contents
Description
sklearn-style standalone tree estimators returning inspectable records
(depth, leaf count, per-feature split usage). fit trains a classifier (from a
TreeConfig) or a regressor (from a RegTreeConfig); predict is the compiled
tree expression, and the record exposes the raw Tree too. The bare
fitDecisionTree remains for callers that only want
the classifier Expr.
Synopsis
- module DataFrame.Model
- data DecisionTreeClassifier a = DecisionTreeClassifier {
- dtcExpr :: !(Expr a)
- dtcDepth :: !Int
- dtcNLeaves :: !Int
- dtcFeatureUsage :: !(Map Text Int)
- data DecisionTreeRegressor = DecisionTreeRegressor {}
