Trade-off between capacity and robustness when varying potential depth <i>r</i>₁.

(A) The storage capacity decreases when the noise strength increases strongly depends on r1. Small values of r1 lead to large storage capacity, but storage is highly sensitive to noise. Large values of r1 lead to small capacity, but storage is highly robust. (B) The trade-off between p0 and R, where p0 is the storage capacity in the absence of noise (r3 = 0), and R quantifies robustness to noise, Eq (14). With deeper potentials, the storage capacity is smaller but storage is more robust. Here, C is optimized for each value of r1 and other parameters are given as: N = 10, 000, r2 = 1, θ = 0, f = 0.5, c = 0.05.
