Researchers have developed a new method to improve the Factorization Machine with Quadratic-Optimization Annealing (FMQA) by addressing issues with initial training data design. When FMQA is used with one-hot encoding for discrete variables, some binary variables may never be activated, leading to incomplete parameter updates. The proposed solution ensures complete marginal bit coverage by using Latin hypercube sampling (LHS) and Sobol' sequences for initial data generation. This approach, demonstrated on a human-powered aircraft wing-shape optimization benchmark, resulted in improved mean final cruising speeds compared to the baseline FMQA, particularly for larger design variable sets.
