Globally Convergent Block Coordinate Descent Algorithms for Semi-Nonnegative Independent Component Analysis
Zhenyu Cai, Wentao Ding, Jianze Li +1
We propose a subgradient-based block coordinate descent (BCD-SubG) framework for nonconvex optimization over products of probability simplices and a closed feasible set, motivated…

Globally Convergent Jacobi-Type Algorithms for Robust Approximate Diagonalization of Higher-Order Cumulant Tensors
Jianze Li, Zhenyu Cai, Wentao Ding +1
The sums of the absolute values of higher-order cumulants are classical contrast functions for independent component analysis (ICA) and lead naturally to robust approximate diagona…
