FeatureScaler

Feature scaling and normalization utilities

Operations

MinMaxScaler
Normalize
StandardScaler

MinMaxScaler # native

Scales features to a [0, 1] range (Min-Max normalization)

function : native : MinMaxScaler(data:Float[,]) ~ Float[,]

Parameters

Name	Type	Description
data	Float	input matrix

Return

Type	Description
Float	scaled matrix with values in [0, 1]

Normalize # native

Normalizes each row to unit norm (L2 normalization)

function : native : Normalize(data:Float[,]) ~ Float[,]

Parameters

Name	Type	Description
data	Float	input matrix

Return

Type	Description
Float	normalized matrix where each row has L2 norm = 1

StandardScaler # native

Standardizes features by removing mean and scaling to unit variance (Z-score normalization)

function : native : StandardScaler(data:Float[,]) ~ Float[,]

Parameters

Name	Type	Description
data	Float	input matrix

Return

Type	Description
Float	standardized matrix with mean=0 and std=1
