Struct MinMaxScaler 

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

The MinMaxScaler

The MinMaxScaler provides an implementation of Transformer which allows us to transform the input data to have a new minimum and maximum per column.

See the module description for more information.

Implementations

impl<T: Float> MinMaxScaler<T>

pub fn new(min: T, max: T) -> MinMaxScaler<T>

Constructs a new MinMaxScaler with the specified scale.

Examples

use rusty_machine::data::transforms::{MinMaxScaler, Transformer};

// Constructs a new `MinMaxScaler` which will give the data
// minimum `0` and maximum `2`.
let transformer = MinMaxScaler::new(0.0, 2.0);

Trait Implementations
