Trait Implementations

impl<I: Borrow<f64>, T: IntoIterator<Item = I>> Basis<T> for Chebyshev

where T::IntoIter: Clone,

fn project(&self, input: T) -> Result<Features>

Project the given input onto the basis.

fn n_features(&self) -> usize

Return the number of features produced by this Basis.

impl Clone for Chebyshev

fn clone(&self) -> Chebyshev

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Combinators for Chebyshev

fn stack<T>(self, other: T) -> Stack<Self, T>

where Self: Sized,

Return a stack of this Basis over another.

fn with_bias(self) -> Stack<Self, Bias>

where Self: Sized,

Return the a stack of this Basis with a single constant feature term.

fn normalise_l0(self) -> L0Normaliser<Self>

where Self: Sized,

Return the original Basis with all activations normalised in L₀.

fn normalise_l1(self) -> L1Normaliser<Self>

where Self: Sized,

Return the original Basis with all activations normalised in L₁.

fn normalise_l2(self) -> L2Normaliser<Self>

where Self: Sized,

Return the original Basis with all activations normalised in L₂.

fn normalise_linf(self) -> LinfNormaliser<Self>

where Self: Sized,

Return the original Basis with all activations normalised in L∞.

impl Debug for Chebyshev

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

Formats the value using the given formatter.

impl<I: Borrow<f64>, T: IntoIterator<Item = I>> EnumerableBasis<T> for Chebyshev

where T::IntoIter: Clone,

fn ith(&self, input: T, index: IndexT) -> Result<ActivationT>

Compute the the i^th element of the projection for the given input.

impl PartialEq for Chebyshev

fn eq(&self, other: &Chebyshev) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Space for Chebyshev

type Value = Features

The data representation of the space.

fn dim(&self) -> Dim

Return the dimensionality of the space.

fn card(&self) -> Card

Return the number of elements in the set comprising the space.
