Comparison of MSE between nonadaptive decoding methods and the corresponding adaptive methods in the testing trials of the two datasets. (a) Gray line is the MSE difference between the nonadaptive Kalman filter and the adaptive Kalman filter in 470 testing trials in dataset 1. Black straight line is the optimal linear fit with a positive slope. (b) Same as (a) except for the comparison between the nonadaptive and adaptive linear regressions. (c) and (d) Same as (a) and (b) except in 290 testing trials in dataset 2.
