Struct Binarizer 

pub struct Binarizer<F> { /* private fields */ }

A stateless feature binarizer.

Values strictly greater than threshold become 1.0; all other values become 0.0. The default threshold is 0.0.

This transformer is stateless — no fitting is needed. Call Transform::transform directly.

Examples

use ferrolearn_preprocess::binarizer::Binarizer;
use ferrolearn_core::traits::Transform;
use ndarray::array;

let binarizer = Binarizer::<f64>::new(0.5);
let x = array![[0.0, 0.5, 1.0]];
let out = binarizer.transform(&x).unwrap();
// out = [[0.0, 0.0, 1.0]]

Implementations

impl<F: Float + Send + Sync + 'static> Binarizer<F>

pub fn new(threshold: F) -> Self

Create a new Binarizer with the given threshold.

pub fn threshold(&self) -> F

Return the configured threshold.

Trait Implementations

impl<F: Clone> Clone for Binarizer<F>

fn clone(&self) -> Binarizer<F>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F: Debug> Debug for Binarizer<F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F: Float + Send + Sync + 'static> Default for Binarizer<F>

fn default() -> Self

Returns the “default value” for a type.

impl<F: Float + Send + Sync + 'static> Transform<ArrayBase<OwnedRepr<F>, Dim<[usize; 2]>>> for Binarizer<F>

fn transform(&self, x: &Array2<F>) -> Result<Array2<F>, FerroError>

Apply the threshold: values > threshold become 1.0, others become 0.0.

Errors

This implementation never returns an error for well-formed inputs.

type Output = ArrayBase<OwnedRepr<F>, Dim<[usize; 2]>>

The transformed output type.

type Error = FerroError

The error type returned by transform.
