Module rusty_machine::data::transforms::standardize

The Standardizing Transformer

This module contains the Standardizer transformer.

The Standardizer transformer is used to transform input data so that the mean and standard deviation of each column are as specified. This is commonly used to transform the data to have 0 mean and a standard deviation of 1.

Examples

use rusty_machine::data::transforms::{Transformer, Standardizer};
use rusty_machine::linalg::Matrix;

// Constructs a new `Standardizer` to map to mean 0 and standard
// deviation of 1.
let mut transformer = Standardizer::default();

let inputs = Matrix::new(2, 2, vec![-1.0, 2.0, 1.5, 3.0]);

// Transform the inputs to get output data with required mean and
// standard deviation.
let transformed = transformer.transform(inputs).unwrap();
