Deep object recognition models have been very successful over benchmark datasets such as ImageNet. How accurate and robust are they to distribution shifts arising from natural and synthetic variations in datasets? Prior research on this problem has primarily focused on ImageNet variations (e.g., ImageNetV2, ImageNet-A). To avoid potential inherited biases in these studies, we take a different approach. Specifically, we reanalyze the ObjectNet dataset recently proposed by Barbu et al. containing objects in daily life situations. They showed a dramatic performance drop of the state of the art object recognition models on this dataset. Due to the importance and implications of their results regarding the generalization ability of deep models, we take a second look at their analysis. We find that applying deep models to the isolated objects, rather than the entire scene as is done in the original paper, results in around 20-30% performance improvement. Relative to the numbers reported in Barbu et al., around 10-15% of the performance loss is recovered, without any test time data augmentation. Despite this gain, however, we conclude that deep models still suffer drastically on the ObjectNet dataset. We also investigate the robustness of models against synthetic image perturbations such as geometric transformations (e.g., scale, rotation, translation), natural image distortions (e.g., impulse noise, blur) as well as adversarial attacks (e.g., FGSM and PGD-5). Our results indicate that limiting the object area as much as possible (i.e., from the entire image to the bounding box to the segmentation mask) leads to consistent improvement in accuracy and robustness.

Decomposition-Based Domain Adaptation for Real-World Font Recognition
我们提出了一个域自适应框架,以解决合成训练和真实世界的测试数据之间的域不匹配。我们展示了我们的方法上一个具有挑战性的细粒度分类问题:识别字体风格的文本图像。在这个任务中,生成大量的渲染字体示例非常容易,但很难获得真实世界的标记图像。在以前的字体识别方法中,这种真实到合成域的差距导致了对新真实数据的泛化能力差(Chen et al.(2014))。在本文中,我们介绍了一种卷积神经网络分解方法,利用一个大型的训练语料库的合成数据,以获得有效的特征进行分类。这是使用基于堆叠卷积自动编码器的自适应技术来完成的,堆叠卷积自动编码器利用大量未标记的真实世界文本图像与以特定方式预处理的合成数据相结合。所提出的DeepFont方法在我们收集的一个新的大型标记真实世界数据集上实现了高于80%(前5名)的准确率。
