摘要:

典型的工程设计任务需要努力迭代地修改设计,直到它们满足某些约束,即,性能或属性要求。过去的工作已经提出了解决逆向设计问题的方法,其中所需的设计直接从指定的要求生成,从而避免了试错过程。在这些方法中,条件深度生成模型显示出巨大的潜力,因为1)它适用于复杂的高维设计,2)它可以在任何条件下生成多个备选设计。在这项工作中,我们提出了一个有条件的深度生成模型,范围GAN,以实现自动设计综合受范围约束。该模型通过引入标签感知的自增强方法解决了数据驱动反设计问题中的稀疏条件问题。我们还提出了一个新的均匀性损失,以确保生成的设计均匀地覆盖给定的要求范围。通过一个真实世界的约束三维形状生成的例子,我们表明,标签感知的自我增强导致的约束满足的平均提高14%的3D形状,和均匀性损失导致的均匀性的125%的平均增加生成的形状的属性。这项工作奠定了基础,数据驱动的反设计问题,我们考虑范围的限制,并有稀疏的区域条件空间。

英文摘要:

Typical engineering design tasks require the effort to modify designs iteratively until they meet certain constraints, i.e., performance or attribute requirements. Past work has proposed ways to solve the inverse design problem, where desired designs are directly generated from specified requirements, thus avoid the trial and error process. Among those approaches, the conditional deep generative model shows great potential since 1) it works for complex high-dimensional designs and 2) it can generate multiple alternative designs given any condition. In this work, we propose a conditional deep generative model, Range-GAN, to achieve automatic design synthesis subject to range constraints. The proposed model addresses the sparse conditioning issue in data-driven inverse design problems by introducing a label-aware self-augmentation approach. We also propose a new uniformity loss to ensure generated designs evenly cover the given requirement range. Through a real-world example of constrained 3D shape generation, we show that the label-aware self-augmentation leads to an average improvement of 14% on the constraint satisfaction for generated 3D shapes, and the uniformity loss leads to a 125% average increase on the uniformity of generated shapes' attributes. This work laid the foundation for data-driven inverse design problems where we consider range constraints and there are sparse regions in the condition space.
