Enum lfa::projection::Projection

pub enum Projection {
    Dense(Vector<f64>),
    Sparse(Vector<usize>),
}

Projected feature vector representation.

Variants

Dense(Vector<f64>)

Dense, floating-point activation vector.

Sparse(Vector<usize>)

Sparse, index-based activation vector.

Methods

impl Projection

fn z(&self) -> f64

Compute the l1 normalisation constant of the projection.

fn activity(&self) -> usize

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

Trait Implementations

impl Debug for Projection

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Projection

fn clone(&self) -> Projection

Returns a copy of the value.

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

Performs copy-assignment from source.
