Enum InitStrategy

}

Initialization strategy for CP-ALS

Variants

Random

Random initialization from uniform distribution [0, 1]

RandomNormal

Random initialization from normal distribution N(0, 1)

Svd

SVD-based initialization (HOSVD)

Nnsvd

Non-negative SVD initialization (NNSVD)

Based on Boutsidis & Gallopoulos (2008). Uses SVD with non-negativity constraints, suitable for non-negative decompositions (e.g., topic modeling, NMF-style).

LeverageScore

Leverage score sampling initialization

Based on statistical leverage scores from SVD. Samples important rows/columns based on their contribution to the low-rank approximation. More principled than random initialization for large-scale tensors.
