Struct rusty_machine::data::transforms::standardize::StandardizerFitter

pub struct StandardizerFitter<T: Float> { /* private fields */ }

A builder used to construct a Standardizer

Implementations

impl<T: Float> StandardizerFitter<T>

pub fn new(mean: T, stdev: T) -> StandardizerFitter<T>

Construct a new StandardizerFitter with specified mean and standard deviation.

Note that this function does not create a Transformer only a builder which can be used to produce a fitted Transformer.

Examples

use rusty_machine::data::transforms::StandardizerFitter;
use rusty_machine::linalg::Matrix;

let fitter = StandardizerFitter::new(0.0, 1.0);

// We can call `fit` from the `transform::TransformFitter`
// trait to create a `Standardizer` used to actually transform data.
use rusty_machine::data::transforms::TransformFitter;
let mat = Matrix::new(2, 2, vec![1.0, 2.0, 3.0, 5.0]);
let transformer = fitter.fit(&mat);
