Fig. 3: Reservoir computing performance of different magnetic phase spaces.
MSE performance comparison of different computation tasks across three distinct physical phases (skyrmion, skyrmion–conical hybrid and conical) at T = 4 K. In a–c, the red dotted and grey curves represent the target functions and the computation results without the physical reservoirs, respectively. Blue, orange and purple curves display calculations with the physical reservoirs of skyrmion, skyrmion–conical hybrid and conical phases, respectively. a, Forecasting a Mackey–Glass chaotic time series of ten steps ahead (MG(N + 10)). b, Nonlinear transformation of a sine-wave input into saw waveforms. c, Combined transform/forecasting of ten future steps of a cubed Mackey–Glass signal. d, Illustration of the mapped field-cycling protocol visualized as a modified boxplot (details in the main text). e,g, Evaluation of MSE values at a constant Hrange as a variation of Hc and T, respectively, for forecasting (MG(N + 10)) (e) and transformation (square wave) (g) target applications. f, Evaluation of MSE values at a constant Hc as a variation of Hrange and T for a transformation (square wave) target application. The colour scale in g also applies to f.
