Abstract
A method and a system for determining a guided random data sampling are disclosed. The method comprises: converting input data into an optical signal with a variable average intensity through a first conversion module; converting the optical signal into a guided optical signal according to guiding data by a photonic computing module, wherein the average intensity of the guided optical signal varies with the average intensity of the optical signal; and converting the guided optical signal into output data and outputting the output data by a second conversion module; wherein the noise generated by at least one of the first conversion module, the photonic computing module, and the second conversion module is added to the output data as a perturbation. By yielding the perturbation in the optical-analog domain, the output data can be quickly converged to an expected solution in the solving operation of the combinatorial optimization problem.
