Struct RescalFactorizer 

pub struct RescalFactorizer { /* private fields */ }

RESCAL Tensor Factorization for predicate invention

Decomposes a 3-way tensor X into: X_k ≈ A × R_k × A^T

Where:

• X_k is the adjacency matrix for relation k
• A contains entity embeddings
• R_k is the core tensor for relation k

Implementations

impl RescalFactorizer

pub fn new(num_entities: usize, dim: usize, num_relations: usize) -> Self

Create a new factorizer

pub fn factorize( &self, triples: &[(usize, usize, usize)], iterations: usize, ) -> RescalResult

Factorize a set of triples

Arguments

• triples - List of (head, relation, tail) indices
• iterations - Number of ALS iterations

Trait Implementations

impl Debug for RescalFactorizer

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

Formats the value using the given formatter.
