WASHH通过动态选择搜索策略,在有限评估下提升连续优化与超参调优效果。
WASHH: An Anchor-Aware Whale-Guided Selection Hyper-Heuristic for Continuous Optimization and SVC Configuration

- 采用鲸鱼优化为主干,动态选择多种搜索行为组合。
- 在30维测试函数上平均排名1.10,8个函数超越原版鲸鱼算法。
- 适合资源受限的自动化机器学习系统,尤其适用于小预算调参。
学习辅助算法设计常需在极小评估预算下做出可靠搜索决策,单一元启发式方法可能不可靠。本文提出WASHH——一种基于鲸鱼优化的自适应选择超启发式方法,用于连续黑盒优化。WASHH以鲸鱼优化(WOA)为主要开发骨干,同时将粒子群风格的记忆、灰狼优化风格的领导者平均、差分进化风格的变异、局部坐标搜索及锚点引导的精炼等作为可选搜索行为。在线奖励控制器根据实际改进情况分配评估资源,而锚点精炼则利用低成本参考配置(如盒子中心或默认模型设置),无需绕过黑盒评估。在10个30维基准函数上,进行10次独立运行、共12,000次评估,WASHH取得最优平均排名1.10,在全部10个函数上表现最佳或并列最佳;在8个函数上严格优于WOA,且在Rastrigin和Griewank函数上达到数值最优。进一步在乳腺癌诊断的SVC超参数配置任务中,于300次评估预算下,WASHH获得最低均值验证对数损失,表明锚点感知的选择型超启发式是轻量级学习辅助系统的一条可行路径。
原文摘要 · Abstract (English)
Learning-assisted algorithm design often has to make reliable search decisions under small evaluation budgets, where committing to a single metaheuristic can be unreliable. We propose WASHH, a Whale-guided Adaptive Selection Hyper-Heuristic for continuous black-box optimization. WASHH uses WOA as the main exploitation backbone, but treats PSO-style memory, GWO-style leader averaging, DE-style variation, local coordinate search, and anchor-guided refinement as selectable search behaviors. An online reward controller allocates evaluations according to observed improvements, while anchor refinement exploits inexpensive reference configurations such as box centers or default model settings without bypassing black-box evaluation. On ten 30-dimensional benchmark functions with 10 independent runs and 12,000 evaluations, WASHH achieves the best average rank, 1.10, and is best or tied best on all ten functions. It strictly improves over WOA on eight functions and ties WOA at the numerical optimum on Rastrigin and Griewank. We further study SVC hyperparameter configuration for breast cancer diagnosis under a 300-evaluation budget. WASHH obtains the lowest mean validation log loss among the compared optimizers, suggesting that anchor-aware selection hyper-heuristics are a practical lightweight direction for LEAD systems.
