Struct StandardScaler 

pub struct StandardScaler {
    pub with_mean: bool,
    pub with_std: bool,
}

Parameters for StandardScaler (unfitted state).

Standardizes features by removing the mean and scaling to unit variance: z = (x - mean) / std

Fields

with_mean: bool

If true, center data to zero mean before scaling.

with_std: bool

If true, scale data to unit variance.

Implementations

impl StandardScaler

pub fn new() -> Self

Create a new StandardScaler with defaults (both centering and scaling enabled).

pub fn with_mean(self, with_mean: bool) -> Self

Set whether to center data to zero mean before scaling.

pub fn with_std(self, with_std: bool) -> Self

Set whether to scale data to unit variance.
