Struct FeatureEncoder 

pub struct FeatureEncoder {
    pub scaler: StandardScaler,
    pub minmax: MinMaxScaler,
    pub quantile: QuantileTransformer,
    pub cyclic: Option<CyclicEncoder>,
}

Preprocessing pipeline combining multiple encoders.

Fields

scaler: StandardScaler

Implementations

impl FeatureEncoder

pub fn new(cyclic_periods: Option<Vec<f32>>) -> Self
