Struct KBinsDiscretizer 

pub struct KBinsDiscretizer {
    pub n_bins: usize,
    pub strategy: BinStrategy,
    pub encode: EncodeStrategy,
}

Parameters for KBinsDiscretizer (unfitted state).

Bins continuous features into discrete intervals. Two binning strategies are supported: uniform-width and quantile-based. Output can be ordinal (bin indices) or one-hot encoded.

Fields

n_bins: usize

Number of bins per feature.

strategy: BinStrategy

Strategy for computing bin edges.

encode: EncodeStrategy

Encoding strategy for the output.

Implementations

impl KBinsDiscretizer

pub fn new() -> KBinsDiscretizer

Create a new KBinsDiscretizer with defaults (5 bins, quantile strategy, ordinal encoding).

pub fn n_bins(self, n_bins: usize) -> KBinsDiscretizer

Set the number of bins.

pub fn strategy(self, strategy: BinStrategy) -> KBinsDiscretizer

Set the binning strategy.

pub fn encode(self, encode: EncodeStrategy) -> KBinsDiscretizer

Set the encoding strategy.
