Abstract
The running time and the convergence between traditional parallel factor trilinear alternating least squares algorithm (TALS) algorithm and complex parallel factor (COMFAC) algorithm is compared by the experiment. The experiment result shows that both methods can obtain good separation performance. However, the traditional parallel factor separation algorithm has the higher complexity and the slower convergence. The complex parallel factor analysis can improve the convergence of the the traditional parallel factor analysis. The solution of complex parallel factor is usually very close to the least squares solution with only a few iterations.
