FPGA-Based Stochastic Echo State Networks for Time-Series Forecasting

Figure 14

Simulation results for the mean square error (MSE) in the fitting task according to the classical and stochastic approaches. The two scanned parameters are and . The number of neurons was fixed to 20. A randomly generated distribution of the input weights was used. The evaluation time is fixed to for the stochastic approach.
