Comparison of computation times and estimated ranks.

The computation times (CPU times) and the estimated ranks are evaluated using three sets of input matrices, similar to the case for Fig. 3 (dim = 145). Parameter k in CV is set to 3.本次实验采用三组输入矩阵对计算耗时（CPU耗时）与估计秩进行评估，实验设置与图3（dim=145）中的场景一致。交叉验证（Cross Validation，CV）中的参数k被设置为3。
