新型零膨胀高斯分布提升稀疏优化算法

作者 PulseAugur 编辑部 · [1 个来源] · 2026-06-19 04:00

研究人员开发了一种新颖的方法来增强优化问题中具有稀疏参数空间的估计分布算法（EDAs）。通过采用多元零膨胀高斯（ZIG）分布，这些算法现在可以有效地处理许多解系数为零的情况。该方法在没有分层假设的情况下联合优化稀疏模式和活动参数值，与现有的稀疏优化技术相比，在Lunar Lander等基准测试中提高了收敛性和性能。 AI

零膨胀高斯分布在估计分布算法中实现参数空间稀疏性

arXiv:2606.19369v1 Announce Type: cross Abstract: Estimation-of-distribution algorithms (EDAs) are a powerful class of evolutionary methods for black-box optimization, especially when little is known about the structure of the objective. Whereas classical evolutionary algorithms …
