Struct Standardize 

pub struct Standardize;

Standardization transform: (y - center) / scale.

Trait Implementations

impl Clone for Standardize

fn clone(&self) -> Standardize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Standardize

impl Debug for Standardize

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

Formats the value using the given formatter.

impl Default for Standardize

fn default() -> Standardize

Returns the “default value” for a type.

impl Eq for Standardize

impl PartialEq for Standardize

fn eq(&self, other: &Standardize) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Standardize

impl TargetTransform for Standardize

type State = StandardizeState

Состояние transform-а, сохраняемое вместе с обученной моделью.

fn fit(y: &[f64]) -> Result<Self::State, TransformError>

Оценивает состояние transform-а по обучающему target.

fn transform(state: &Self::State, y: f64) -> f64

Преобразует одно значение target.

fn inverse(state: &Self::State, value: f64) -> f64

Возвращает значение на исходную шкалу.

fn fit_transform(y: &[f64]) -> Result<(Self::State, Vec<f64>), TransformError>

Оценивает состояние и преобразует весь target.

fn transform_slice( state: &Self::State, y: &[f64], ) -> Result<Vec<f64>, TransformError>

Преобразует срез target в новый Vec.

fn transform_into( state: &Self::State, y: &[f64], out: &mut [f64], ) -> Result<(), TransformError>

Преобразует срез target в caller-provided output buffer.

fn inverse_slice( state: &Self::State, values: &[f64], ) -> Result<Vec<f64>, TransformError>

Возвращает срез значений на исходную шкалу в новый Vec.

fn inverse_into( state: &Self::State, values: &[f64], out: &mut [f64], ) -> Result<(), TransformError>

Возвращает transform-scale values на исходную шкалу в caller-provided buffer.
