lazymatrix::RowNormalization

LazyMatrix for Rust · 0.9.0

Source

pub struct RowNormalization

A row normalization specification with independent Centering and Scaling choices.

The default performs no centering or scaling. Norms (L1, L2, and MaxAbs) are fitted to centered rows when centering is active. Standard deviations, ranges, and quantile ranges are translation-invariant. Use crate::RowNormalizedMatrix::new to fit each row independently.

Fields

center

pub center: Centering

Source

How to center each row.

scale

pub scale: Scaling

Source

How to scale each row.

Inherent implementation

Source

impl RowNormalization

min_max

pub const fn min_max() -> Self

Source

Subtract each row's minimum and divide by its range.

Finite, nonconstant rows span [0, 1] on the fitting data. Fitting replaces exact zero ranges with one, so finite constant rows become zero. Reusing parameters does not clip values to [0, 1].

new

pub const fn new(center: Centering, scale: Scaling) -> Self

Source

Build a specification from its centering and scaling choices.

robust

pub fn robust() -> Self

Source

Subtract each row's median and divide by its interquartile range.

Quantiles use linear interpolation at (ncols - 1) * q. There is no standard-normal calibration. Fitting replaces exact zero ranges with one. Use Self::new with Scaling::QuantileRange for custom bounds.

standardize

pub const fn standardize() -> Self

Source

Subtract each row's mean and divide by its population standard deviation.

The variance uses ncols as its divisor. Fitting replaces exact zero scales with one, so finite constant rows become zero. For sample standard deviations, use Self::new(Centering::Mean, Scaling::Sd { df: 1 }).
