From: Low-power scalable multilayer optoelectronic neural networks enabled with incoherent light
a Example propagation of a trained miniaturized MNIST digit through the three-layer network. Digital simulation values are compared to the analog experimental values. b Correlation between simulation and experiment of activations in Hidden layer 1 in response to individual miniaturized MNIST digits (c) Same as (b), but in Hidden layer 2. d Confusion matrix of estimated classes for simulated results, in percent. e Same as (d), but for experimental results.
