Researchers have investigated the effectiveness of the "edge of chaos" heuristic in designing reservoir computers for forecasting tasks. Their analysis, using the spectral radius as a control parameter, revealed that the optimal radius for forecasting performance does not align with the Lyapunov edge. Instead, they identified that target dynamics are primarily represented by stable Lyapunov modes, whose stability is influenced by the input. This led to the development of a stability-expressivity transfer index, which accurately predicts the optimal spectral radius for autonomous forecasting across various target dynamics and reservoir types.
