AI总结:

本文提出了一种面向成本的贝叶斯优化方法,通过利用设计师估计的成本来指导原型制作,从而在降低成本的同时提高设计效率。

摘要:

在迭代设计中,决定哪些想法值得原型化是一个核心问题。原型应在预期改进高且成本低时生产。然而,这种决策困难,因为成本差异极大:简单的参数调整可能只需几秒钟,而制造硬件则消耗材料和能源。这种不对称性可能会抑制设计师探索设计空间的积极性。在本文中,我们提出了一种扩展的面向成本的贝叶斯优化方法,以应对多样化的原型制作成本。该方法基于贝叶斯优化的强大功能,仅需对获取函数进行最小修改。关键思想是利用设计师估计的成本来引导采样,使原型更加经济有效。在技术评估中,该方法在成本仅为约70%的情况下,其效用与无成本意识的基线方法相当;在严格预算下,其表现优于基线方法三倍。在12名参与者参与的现实 joysticks 设计任务中进行了内组研究,展示了相似的益处。这些结果表明,考虑原型制作成本可以使贝叶斯优化更符合现实世界的设计项目。

英文摘要:

Deciding which idea is worth prototyping is a central concern in iterative design. A prototype should be produced when the expected improvement is high and the cost is low. However, this is hard to decide, because costs can vary drastically: a simple parameter tweak may take seconds, while fabricating hardware consumes material and energy. Such asymmetries, can discourage a designer from exploring the design space. In this paper, we present an extension of cost-aware Bayesian optimization to account for diverse prototyping costs. The method builds on the power of Bayesian optimization and requires only a minimal modification to the acquisition function. The key idea is to use designer-estimated costs to guide sampling toward more cost-effective prototypes. In technical evaluations, the method achieved comparable utility to a cost-agnostic baseline while requiring only ${\approx}70\%$ of the cost; under strict budgets, it outperformed the baseline threefold. A within-subjects study with 12 participants in a realistic joystick design task demonstrated similar benefits. These results show that accounting for prototyping costs can make Bayesian optimization more compatible with real-world design projects.
