论文摘要
我们考虑了一种受约束的优化问题,其中违反约束会导致不可撤销的损失,例如破裂有价值的实验资源/平台或人类生命的丧失。此类问题称为安全优化问题(SAFEOPS)。尽管SafeOps近年来已经在机器学习社区中受到了关注,但尽管在2009年至2011年之间进行了一些早期尝试,但对进化计算(EC)社区的兴趣不大。此外,缺乏可接受的准则,即如何为SafeOps的不同算法进行不同的算法,EC社区具有更高的兴趣型的兴趣和良好的兴趣。在EC社区中的这个问题类别。为此,我们(i)提供了对安全件的正式定义,并将其与EC社区所熟悉的其他类型的优化问题进行了对比,(ii)调查关键安全参数对所选安全优化算法的性能的影响,(iii)基准测试EC与先进的安全优化算法对机器学习社区的安全优化算法以及(iv)的开放式(IIV)提供了一个开放式工程。
We consider a type of constrained optimization problem, where the violation of a constraint leads to an irrevocable loss, such as breakage of a valuable experimental resource/platform or loss of human life. Such problems are referred to as safe optimization problems (SafeOPs). While SafeOPs have received attention in the machine learning community in recent years, there was little interest in the evolutionary computation (EC) community despite some early attempts between 2009 and 2011. Moreover, there is a lack of acceptable guidelines on how to benchmark different algorithms for SafeOPs, an area where the EC community has significant experience in. Driven by the need for more efficient algorithms and benchmark guidelines for SafeOPs, the objective of this paper is to reignite the interest of this problem class in the EC community. To achieve this we (i) provide a formal definition of SafeOPs and contrast it to other types of optimization problems that the EC community is familiar with, (ii) investigate the impact of key SafeOP parameters on the performance of selected safe optimization algorithms, (iii) benchmark EC against state-of-the-art safe optimization algorithms from the machine learning community, and (iv) provide an open-source Python framework to replicate and extend our work.
