Struct lfa::SparseActivations

pub struct SparseActivations {
    pub dim: usize,
    pub activations: HashMap<IndexT, ActivationT>,
}

Internal type used to represent a sparse feature vector.

Fields

dim: usize

The total number of features.

activations: HashMap<IndexT, ActivationT>

The subset of active features and their activations.

Implementations

impl SparseActivations

pub fn iter(&self) -> Iter<IndexT, ActivationT>

An iterator visiting all feature-activation pairs in arbitrary order. The iterator element type is (&'a IndexT, &'a ActivationT).

Trait Implementations

impl Clone for SparseActivations

fn clone(&self) -> SparseActivations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SparseActivations

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

Formats the value using the given formatter.

impl From<SparseActivations> for Features

fn from(sa: SparseActivations) -> Features
