a Four independent input streams (left), each consisting of eight spike trains generated by poisson process with randomly varying rates $r_i(t),i=1,\dots 4$; The rates of four input streams are plotted in curves with corresponding colors (right), where all rates are given in the unit of Hz. b The firing activity of 400 neurons in the liquid network with spiking dynamic (left) or bursting dynamic (right). c Corresponding computational performance of the linear readouts (red dashed line) which were trained according to the teaching signal $r_1+r_3$ (blue line).
