"combines temporal encoding with low-loss, partially reflective fiber... scalable, processing multiple neurons simultaneously... high-speed, compact, 100 to 1,000X lower power use... apply random weights efficiently scattering light off: rough surface, or non-uniformities in optical fiber... process high bandwidth data that is difficult to record and analyze real-time (high-resolution image data using passive random convolution projections, RF data for electronic warfare), implementing machine learning algorithms faster"
