Fig 5. The effect of noise and uncertainty in inputs and weights.

(A) Impact of additive noise and spike jitter in the input, quantified by the minimum loss achieved within 100 generations. This is shown for weights-delays, weights-time constants, delays-time constants and weights-delays-time constants mutated solutions. (B) Robustness of solutions trained to minimize noise in weights quantified by the minimum loss in 1000 generations, with each loss averaged over 100 trials. This is shown for weights only, weights-delays, weights-time constants and weights-delays-time constants mutated solutions. For more details, see Tables G and H in S1 Text and the related text.
