Struct FittedOneHotEncoder 

pub struct FittedOneHotEncoder { /* private fields */ }

Fitted OneHotEncoder — holds the number of unique categories per column.

Implementations

impl FittedOneHotEncoder

pub fn transform( &self, x: &ArrayBase<OwnedRepr<usize>, Dim<[usize; 2]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, RustMlError>

Each input column of k categories is expanded into k binary columns.

pub fn categories(&self) -> &[usize]

Return the number of categories per original column.

pub fn n_output_features(&self) -> usize

Return the total number of output columns after one-hot encoding.
