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 backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl<'a, F: Float, O: 'a> 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>>, 

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

Performs the conversion.
