Struct CPDecomposition 

Source 
pub struct CPDecomposition {
    pub weights: FixedVector,
    pub factors: Vec<FixedMatrix>,
}
Expand description

CP (Canonical Polyadic) decomposition: T ≈ Σ_r λ_r a₁_r ∘ a₂_r ∘ … ∘ a_N_r

Decomposes a tensor into a sum of R rank-1 terms. Each term is an outer product of vectors, weighted by λ_r.

Fields§

§weights: FixedVector

Component weights (R values).

§factors: Vec<FixedMatrix>

Factor matrices: factors[n] is d_n × R (columns are the rank-1 vectors).

Implementations§

Source§

impl CPDecomposition
