Description:

Ext-RESCAL is a memory efficient implementation of RESCAL, a state-of-the-art algorithm for DEDICOM-like tensor factorization. Ext-RESCAL is written in Python and relies on the SciPy Sparse module.

  • 3-D sparse tensor factorization [1];
  • Joint 3-D sparse tensor and 2-D sparse matrix factorization (extended version) [2];
  • The implementation provably scales well to the domains with millions of nodes on the affordable hardware;
  • Handy input format;
