研究人员推出了一种新颖的算法SPARROW，专为低预算黑盒优化而设计。与需要大量评估才能将生成模型与奖励信号对齐的现有方法不同，SPARROW将生成先验与奖励信号解耦。这使得它能够利用任何具有已知损坏过程和预训练数据的采样器作为固定算子。该算法使用对已评估候选者的基于排名的反馈来指导优化，即使在奖励信号嘈杂或不可靠以及搜索空间复杂的情况下也证明是有效的。 AI
影响 这项新的优化技术可以在资源受限的环境中实现更高效的AI模型训练和超参数调整。

Black-box optimization is a fundamental science and engineering tool that makes it possible to optimize objectives without gradient information. Unfortunately, as it often requires many function evaluations, it can be challenging when each one is costly. This is especially true w…
