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

Figure 17

Simulation results for the normalized mean square error (NMSE) in the time-series prediction task according to the deterministic and stochastic approaches. The two scanned parameters are and . The number of neurons was fixed to 50. A randomly generated distribution of the input weights was used. The evaluation time is fixed to for the stochastic approach.
