Decision Tree

Implementations

impl<T: RealNumber> DecisionTreeClassifier<T>

pub fn fit<M: Matrix<T>>(
    x: &M,
    y: &M::RowVector,
    parameters: DecisionTreeClassifierParameters
) -> Result<DecisionTreeClassifier<T>, Failed>

Build a decision tree classifier from the training data.

• x - NxM matrix with N observations and M features in each observation.
• y - the target class values

pub fn predict<M: Matrix<T>>(&self, x: &M) -> Result<M::RowVector, Failed>

Predict class value for x.

• x - KxM data where K is number of observations and M is number of features.
