1. An optical computing device, comprising:
a parametric oscillator array comprising two ends and configured to:
receive a first group of signals; and
generate, based on the first group of signals, a first group of optical signals comprising a plurality of first optical signals;
an interaction computing array coupled to the parametric oscillator array and configured to:
receive the first group of optical signals; and
perform, based on a preset matrix, a first matrix operation on the first group of optical signals to obtain a second group of optical signals that comprises a plurality of second optical signals;
a first feedback system coupled to the two ends and configured to;
receive the first group of optical signals; and
transmit the first group of optical signals to the parametric oscillator array; and
a second feedback system coupled to the parametric oscillator array and the interaction computing array and configured to:
receive the second group of optical signals; and
transmit the second group of optical signals to the parametric oscillator array.
