Extended Data Fig. 8

a, The internal states and final output with the input digit of ‘5’ from the MNIST test set (left), and the output differences between the numerical model and physical system of blocks 1, 2, and 3 with and without SEPNs by using pixel-level statistics (right). b, Output differences averaged over all samples from the MNIST test set with and without SEPNs. See Supplementary Section 8 for a detailed description.
