Struct HoeffdingClassifierConfig 

pub struct HoeffdingClassifierConfig {
    pub max_depth: usize,
    pub delta: f64,
    pub grace_period: usize,
    pub n_bins: usize,
    pub n_features: usize,
    pub max_classes: usize,
}

Available on crate feature alloc only.

Configuration for HoeffdingTreeClassifier.

Use HoeffdingClassifierConfig::builder() to construct with defaults and override only the parameters you need.

Fields

max_depth: usize

Maximum tree depth.

delta: f64

Hoeffding bound confidence parameter (1 - delta). Lower = more splits.

grace_period: usize

Minimum samples at a leaf before considering a split.

n_bins: usize

Number of histogram bins per feature for split evaluation.

n_features: usize

Number of features (0 = lazy init from first sample).

max_classes: usize

Maximum number of classes (0 = auto-discover).
