New FMQA framework uses stage-dependent encoding for black-box optimization

Researchers have developed a stage-dependent framework for factorization machine with quadratic-optimization annealing (FMQA) to improve black-box optimization. This new approach allows for different integer-binary encodings to be used during the surrogate learning phase and the Ising machine solution search phase, addressing the limitation of conventional FMQA which uses a single encoding throughout. The proposed framework, evaluated on the Rastrigin function, demonstrated that one-hot encoding is crucial for learning stage performance, consistently yielding lower residual errors. Further improvements were observed by switching to domain-wall encoding for the solution search phase under finer discretization levels. AI

IMPACT This research could lead to more efficient optimization techniques for complex problems in machine learning.

    Stage-dependent integer-binary encoding in factorization-machine black-box optimization

    Black-box optimization (BBO) deals with problems where objective functions lack explicit analytical forms and are expensive to evaluate. Factorization machine with quadratic-optimization annealing (FMQA) constructs a surrogate model using a factorization machine (FM) and optimize…
