非负张量分解的不平衡乘性更新

The Imbalance Multiplicative Update for Nonnegative Tensor Factorization

针对非负张量分解的乘性更新算法,讨论了其元素形式与矩阵形式的一致性,并给出了不平衡的乘性更新算法.数值试验表明,新的算法具有更快的收敛性.

In this paper, we discuss that the element form coincides with the matrix form in multiplicative update for nonnegative tensor factorization, and propose a imblance multiplica- rive update algorithm. Numerical experiments represent that our new method converge faster than original algorithm.
