Trait Implementations

impl Clone for Fourier

fn clone(&self) -> Fourier

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Projector<[f64]> for Fourier

fn project(&self, input: &[f64]) -> Projection

Project data from an input space onto the basis.

fn dim(&self) -> usize

Return the number of dimensions in the basis space.

fn size(&self) -> usize

Return the number of features in the basis space.

fn activity(&self) -> usize

Return the maximum number of active features in the basis space.

fn equivalent(&self, other: &Self) -> bool

Check for equivalence with another projector of the same type.

fn project_expanded(&self, input: &I) -> Vector<f64>

Project data from an input space onto the basis and convert into a raw, dense vector.

fn expand_projection(&self, projection: Projection) -> Vector<f64>

Expand and normalise a given projection, and convert into a raw, dense vector.
