Struct Normalizer

Source

pub struct Normalizer { /* private fields */ }

Expand description

Represents a fitted normalization model that can transform new data

Implementations§

Source §

impl Normalizer

Source

pub fn new(method: NormalizationMethod, axis: usize) -> Self

Creates a new Normalizer with the specified method and axis

§Arguments

method - The normalization method to apply
axis - The axis along which to normalize (0 for columns, 1 for rows)

§Returns

A new Normalizer instance

Source

pub fn fit<S>(&mut self, array: &ArrayBase<S, Ix2>) -> Result<()>
where S: Data, S::Elem: Float + NumCast,

Fits the normalizer to the input data

§Arguments

array - The input 2D array to fit the normalizer to

§Returns

Result<()> - Ok if successful, Err otherwise

Source

pub fn transform<S>(&self, array: &ArrayBase<S, Ix2>) -> Result<Array2<f64>>
where S: Data, S::Elem: Float + NumCast,

Transforms the input data using the fitted normalizer

§Arguments

array - The input 2D array to transform

§Returns

Result<Array2<f64>> - The transformed array

Source

pub fn fit_transform<S>( &mut self, array: &ArrayBase<S, Ix2>, ) -> Result<Array2<f64>>
where S: Data, S::Elem: Float + NumCast,

Fits the normalizer to the input data and transforms it

§Arguments

array - The input 2D array to fit and transform

§Returns

Result<Array2<f64>> - The transformed array
