ALEXANDRIA, Va., July 21 -- United States Patent no. 12,688,407, issued on July 21, was assigned to Massachusetts Institute of Technology (Cambridge, Mass.).

"Radio-frequency photonic architecture for deep neural networks, signal processing, and computing" was invented by Ronald A. Davis (Las Cruces, N.M.) and Dirk Robert Englund (Brookline, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A multiplicative analog frequency transform optical neural network (MAFT-ONN) encodes data in the frequency domain, achieves matrix-vector products in a single shot using photoelectric multiplication, and uses a single electro-optic modulator for the nonlinear activation of all neurons in each layer. Photoelectric mult...
