Abstract

The present disclosure provides methods and systems for stochastic optimization of a robust inference problem using a sampling device. Specifically, the methods and systems of the present disclosure enable smoothing of objective functions, thereby making such functions amenable to computation via stochastic-gradient methods using sampling in place of solving the inference problem exactly. Such methods and systems advantageously connect the gradient of the smoothed function approximation to a Boltzmann distribution, which can be sampled by a sampling device, such as a Gibbs sampler, using a simulated process and / or quantum process, in particular quantum-annealing process, thermal or adiabatic relaxation of a classical computer, semi-classical computer, or a quantum processor / device, and / orother physical process.

Description

[0001] cross reference [0002] This application claims priority to U.S. Provisional Application No. 62 / 593,563, filed December 1, 2017, and U.S. Patent Application No. 62 / 716,041, filed August 8, 2018, each of which is incorporated by reference in its entirety at this. Background technique [0003] In various engineering domains, robust inference problems are often too complex to be solved directly numerically, even when direct mathematical models can exist. Stochastic optimization is a method for minimizing or maximizing functions that uses stochasticity to partially evaluate constituent functions and can thus be suitable for optimizing very complex models. Contents of the invention [0004] The methods and systems of the present disclosure advantageously enable the smoothing of various objective functions in robust inference problems, making these functions suitable for computation by stochastic gradient methods using sampling instead of solving the inference problems e...
