impl<'a, F: Float, O> FitWith<'a, ArrayBase<OwnedRepr<F>, Dim<[usize; 2]>>, ArrayBase<OwnedRepr<bool>, Dim<[usize; 1]>>, PlattError> for PlattValidParams<F, O>

source§

fn fit_with( &self, obj: O, ds: &DatasetBase<Array2<F>, Array1<bool>> ) -> Result<Self::ObjectOut, PlattError>

Calibrate another model with Platt scaling

This function takes another model and binary decision dataset and calibrates it to produce probability values. The returned model therefore implements the prediction trait for probability targets.

type ObjectOut = Platt<F, O>

impl From<Error> for PlattError

source§

fn from(source: Error) -> Self

Converts to this type from the input type.
