Abstract
A photonics reservoir computing system is described. The system is configured for propagating at least one optical signal so as to create resulting radiation signals in the output channels. The photonics reservoir computing system further comprises weighting elements for weighting signals from the output channels, and at least one optical detector for optically detecting signals from the output channels. The system is adapted for estimating signals from the output channels through an output of the optical detector.
Claims9
A photonics reservoir computing system comprising a training module and a plurality of output channels, the reservoir computing system being configured for propagating at least one optical signal so as to create resulting radiation signals in the output channels, the training module further comprising:
- weighting elements for weighting the radiation signals in the output channels in an optical domain,
- a combining stage for creating a combination of the weighted radiation in the optical domain, and
- at least one optical detector for optically detecting said combination of the weighted radiation signals,
- wherein the training module is configured for iterating over training data several times while adjusting the weighting elements according to a predetermined pattern, thereby estimating the resulting radiation signals in the output channels through an output of the at least one optical detector.
