Struct OMPEncoder 

pub struct OMPEncoder { /* private fields */ }

Orthogonal Matching Pursuit encoder

Implementations

impl OMPEncoder

pub fn new(config: OMPConfig) -> Self

pub fn encode( &self, dictionary: &Array2<Float>, signal: &Array1<Float>, ) -> Result<OMPResult>

Perform OMP sparse coding

Orthogonal Matching Pursuit is a greedy algorithm for sparse approximation. It iteratively selects the dictionary atom most correlated with the residual, then updates coefficients via least squares projection.

Arguments

• dictionary - Dictionary matrix where each column is an atom (n_features × n_atoms)
• signal - Signal to encode (n_features)

Returns

Sparse representation with coefficients, residual norm, and iteration count
