Image completion with large-scale free-form missing regions is one of the most challenging tasks for the computer vision community. While researchers pursue better solutions, drawbacks such as pattern unawareness, blurry textures, and structure distortion remain noticeable, and thus leave space for improvement. To overcome these challenges, we propose a new StyleGAN-based image completion network, Spectral Hint GAN (SH-GAN), inside which a carefully designed spectral processing module, Spectral Hint Unit, is introduced. We also propose two novel 2D spectral processing strategies, Heterogeneous Filtering and Gaussian Split that well-fit modern deep learning models and may further be extended to other tasks. From our inclusive experiments, we demonstrate that our model can reach FID scores of 3.4134 and 7.0277 on the benchmark datasets FFHQ and Places2, and therefore outperforms prior works and reaches a new state-of-the-art. We also prove the effectiveness of our design via ablation studies, from which one may notice that the aforementioned challenges, i.e. pattern unawareness, blurry textures, and structure distortion, can be noticeably resolved. Our code will be open-sourced at: https://github.com/SHI-Labs/SH-GAN.

为化疗中的许多重要任务收集标记数据是耗时的，需要昂贵的实验。近年来，机器学习已被用来使用大规模未标记的分子数据集学习分子的丰富表示，并转移知识，以解决有限数据集的更具挑战性的任务。变形AutoEncoders是已经提出用于进行化学性质预测和分子产生任务的转移的工具之一。在这项工作中，我们提出了一种简单的方法，可以通过在变形自身偏析者学习的表示中包含关于相关分子描述符的附加信息来改善机器学习模型的化学性质预测性能。我们验证了三个属性预测的方法询问。我们探讨了合并的描述符的数量，描述符和目标属性之间的相关性，数据集等的尺寸的影响。最后，我们显示了性能预测模型的性能与属性预测数据集之间的距离和更大的未标记之间的关系。 DataSet在表示空间中。
