Trait lfa::basis::Basis

pub trait Basis<T>: Space + Combinators {
    fn project(&self, input: T) -> Result<Self::Value>;

    fn n_features(&self) -> usize { ... }
}

Trait for functional bases.

Required methods

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

use lfa::{Features, basis::{Basis, Bias}};

let basis = Bias::unit();

assert_eq!(
    basis.project(&[0.0]).unwrap(),
    Features::from(vec![1.0])
);
