Impulsive noise is an important challenge for the practical implementation of active noise control (ANC) systems. The advantages and disadvantages of popular filtered-X least mean square (FXLMS) ANC algorithm and nonlinear filtered-X least ...
Robust Satisficing Linear Regression: performance/robustness trade-off and consistency criterion [0.03%]
鲁棒满意线性回归：性能/健壮性折中与一致性准则
