a Input pre-processed signal (grey data set) and the corresponding output signal (red data set) of the strain-mediated reservoir. b NRMSE as a function of horizontal prediction step i, shown in log scale, for the testing set by using the basic method (black curve) and the optimized algorithm (red curve) for output reconstruction. c and d are the selected predicting results (black) for horizontal step i = 1 (for short-term prediction) and 20 (for long-term prediction), respectively, predicted by the strain-mediated RC system using basic method for output reconstruction, in comparison with the ground truth (blue) of MG time series. e and f are the selected predicting (red) results for horizontal step i = 1 and 20, respectively, predicted by the strain-mediated RC system using optimized algorithm for output reconstruction, in comparison with the ground truth (blue) of MG time series.
