Struct FittedLabelEncoder 

pub struct FittedLabelEncoder { /* private fields */ }

Fitted LabelEncoder — holds the learned vocabulary and mapping.

Implementations

impl FittedLabelEncoder

pub fn transform( &self, labels: &[String], ) -> Result<ArrayBase<OwnedRepr<usize>, Dim<[usize; 1]>>, RustMlError>

Transform string labels into integer-encoded values.

pub fn inverse_transform( &self, encoded: &ArrayBase<OwnedRepr<usize>, Dim<[usize; 1]>>, ) -> Result<Vec<String>, RustMlError>

Inverse-transform integer-encoded values back to string labels.

pub fn vocab(&self) -> &[String]

Return the learned vocabulary (sorted).

pub fn num_classes(&self) -> usize

Return the number of classes.
