New surrogate method enhances stochastic optimization with adaptive designs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel learning-based surrogate method to tackle complex stochastic optimization problems with decision-dependent uncertainty. This approach integrates simulation and statistical learning, using adaptive random designs to improve Jacobian estimates and enhance convergence rates. The proposed Learning-based Stochastic Prox-Linear (L-SPL) algorithm demonstrates superior sample efficiency and achieves lower objective values compared to existing methods, suggesting that tailored statistical designs can significantly boost optimization performance.

    Learning-Based Surrogate Method for Stochastic Optimization under Decision-Dependent Uncertainty with Adaptive Random Designs

    arXiv:2505.07298v2 Announce Type: replace-cross Abstract: We study stochastic programs in which the latent decision-dependent uncertainty is described via a nonparametric regression model. The major challenge is that, without convexity assumptions on either the cost function or t…
