Trait Implementations

impl Clone for PlattError

fn clone(&self) -> PlattError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlattError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PlattError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PlattError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

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

where O: PredictInplace<Array2<F>, Array1<F>> + 'a,

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 ObjectIn = O

type ObjectOut = Platt<F, O>

impl From<Error> for PlattError

fn from(source: Error) -> Self

Converts to this type from the input type.
