}Expand description
Trait for basis projectors.
Required Methods§
sourcefn project(&self, input: &I) -> Projection
fn project(&self, input: &I) -> Projection
Project data from an input space onto the basis.
use lfa::basis::{Projector, Projection, fixed::Constant};
let projector = Constant::ones(2);
assert!(projector.project(&[0.0]).is_dense());
assert_eq!(
projector.project(&[0.0]),
Projection::from(vec![1.0, 1.0])
);Provided Methods§
sourcefn project_expanded(&self, input: &I) -> DenseT
fn project_expanded(&self, input: &I) -> DenseT
Project data from an input space onto the basis and expand into a dense
vector form using Projection::expanded(self.dim()).
use lfa::basis::{Projector, Projection, fixed::Indices};
let projector = Indices::new(2, vec![0, 1]);
assert!(projector.project(&[0.0]).is_sparse());
assert_eq!(
projector.project(&[0.0]),
Projection::from(vec![0, 1]),
);
assert_eq!(
projector.project_expanded(&[0.0]),
vec![1.0, 1.0].into(),
);
