Struct FittedDictionaryLearning 

pub struct FittedDictionaryLearning { /* private fields */ }

A fitted dictionary learning model.

Created by calling Fit::fit on a DictionaryLearning. The learned dictionary is accessible via FittedDictionaryLearning::components. Implements Transform<Array2<f64>> to compute sparse codes for new data.

Implementations

impl FittedDictionaryLearning

pub fn components(&self) -> &Array2<f64>

The learned dictionary, shape (n_components, n_features).

pub fn n_iter(&self) -> usize

Number of iterations performed.

pub fn reconstruction_err(&self) -> f64

The reconstruction error at convergence.

Trait Implementations

impl Clone for FittedDictionaryLearning

fn clone(&self) -> FittedDictionaryLearning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FittedDictionaryLearning

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

Formats the value using the given formatter.

impl Transform<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>> for FittedDictionaryLearning

fn transform(&self, x: &Array2<f64>) -> Result<Array2<f64>, FerroError>

Compute sparse codes for new data using the learned dictionary.

Errors

Returns FerroError::ShapeMismatch if the number of features does not match the dictionary.

type Output = ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>

The transformed output type.

type Error = FerroError

The error type returned by transform.
