Implementations§
Source§impl DecisionTree
impl DecisionTree
Sourcepub fn fit_regressor(
x: &[f64],
y: &[f64],
n: usize,
p: usize,
params: TreeParams,
) -> Result<Self, LearningError>
pub fn fit_regressor( x: &[f64], y: &[f64], n: usize, p: usize, params: TreeParams, ) -> Result<Self, LearningError>
Fit a regression tree (Criterion::Mse).
Sourcepub fn fit_classifier(
x: &[f64],
y: &[usize],
n: usize,
p: usize,
params: TreeParams,
) -> Result<Self, LearningError>
pub fn fit_classifier( x: &[f64], y: &[usize], n: usize, p: usize, params: TreeParams, ) -> Result<Self, LearningError>
Fit a classification tree (Criterion::Gini); labels are small integers.
Sourcepub fn predict_row(&self, q: &[f64]) -> f64
pub fn predict_row(&self, q: &[f64]) -> f64
Raw leaf prediction (regression value, or class label as f64) for one row.
pub fn predict(&self, x: &[f64], m: usize) -> Vec<f64>
Sourcepub fn predict_class(&self, q: &[f64]) -> usize
pub fn predict_class(&self, q: &[f64]) -> usize
Class label prediction (rounds the leaf value) for a classifier tree.
pub fn criterion(&self) -> Criterion
