lazymatrix::NormalizationParams

LazyMatrix for Rust · 0.8.1

Source

pub struct NormalizationParams<F = f64>

Fitted column normalization, reusable on matrices with the same column count.

Present scales are nonzero. Computed normalization replaces exact zero scales with one before constructing these parameters. Explicit parameters preserve negative scales and nonfinite values.

Inherent implementation

Source

impl<F: lazymatrix::Scalar> NormalizationParams<F>

centers

pub fn centers(&self) -> Option<&[F]>

Source

Fitted column centers, if centering is active.

from_parts

pub fn from_parts(
    ncols: usize,
    centers: Option<Vec<F>>,
    scales: Option<Vec<F>>
) -> Self

Source

Construct validated explicit parameters.

Panics

Panics if either vector has a different length from ncols, or if a scale is exact positive or negative zero.

into_parts

pub fn into_parts(self) -> NormalizationStats<F>

Source

Recover the fitted centers and scales without copying.

ncols

pub fn ncols(&self) -> usize

Source

Number of columns these parameters describe.

scales

pub fn scales(&self) -> Option<&[F]>

Source

Fitted column scales, if scaling is active.
