Fully Scalable Methods for Distributed Tensor Factorization


CDTF (Coordinate Descent for Tensor Factorization) and SALS (Subset Alternating Least Square) are CDTF has an advantage in terms of memory usage and flexibility, while SALS has an advantage in terms of convergence speed


CDTF and SALS are described in the following papers:
