Abstract:
We show that the capacity of the Ising perceptron is with high probability upper bounded by the constant $alpha approx 0.833$ conjectured by Krauth and Mézard, under the condition that an explicit two-variable function $S(lambda_1,lambda_2)$ is maximized at (1,0). The earlier work of Ding and Sun proves the matching lower bound subject to a similar numerical condition, and together these results give a conditional proof of the conjecture of Krauth and Mézard.
