Struct TargetEncoding 

pub struct TargetEncoding {
    pub levels: Vec<String>,
    pub ratios: Vec<f64>,
    pub k: f64,
}

The encoding of each level learned from all the training rows, from target_encode; encode applies it to new data.

Fields

levels: Vec<String>

The levels seen in training, sorted.

ratios: Vec<f64>

Each level’s credibility-weighted actual-to-expected ratio.

k: f64

The credibility constant K.

Implementations

impl TargetEncoding

pub fn encode(&self, values: &[String]) -> Vec<f64>

The encoding of each value; a level not seen in training gets 1, no credibility.
