A great interest has arisen in using Deep Generative Models (DGM) for generative design. When assessing the quality of the generated designs, human designers focus more on structural plausibility, e.g., no missing component, rather than visual artifacts, e.g., noises in the images. Meanwhile, commonly used metrics such as Fr\'echet Inception Distance (FID) may not evaluate accurately as they tend to penalize visual artifacts instead of structural implausibility. As such, FID might not be suitable to assess the performance of DGMs for a generative design task. In this work, we propose to encode the input designs with a simple Denoising Autoencoder (DAE) and measure the distribution distance in the latent space thereof. We experimentally test our DAE-based metrics with FID and other state-of-the-art metrics on three data sets: compared to FID and some more recent works, e.g., FD$_\text{DINO-V2}$ and topology distance, DAE-based metrics can effectively detect implausible structures and are more consistent with structural inspection by human experts.

使用深度生成模型（DGM）进行生成设计的研究表明，常用的评估指标往往不能准确评估结构不合理性，本研究提出基于简单去噪自编码器（DAE）的度量方法，在三个数据集上与Fréchet Inception Distance和其它先进指标进行对比实验，结果表明基于DAE的指标能够有效检测不合理的结构并与人工专家的结构检查结果相一致。
