Mammalian brains handle complex reasoning tasks in a gestalt manner by integrating information from regions of the brain that are specialised to individual sensory modalities. This allows for improved robustness and better generalisation ability. In contrast, deep neural networks are usually designed to process one particular information stream and susceptible to various types of adversarial perturbations. While many methods exist for detecting and defending against adversarial attacks, they do not generalise across a range of attacks and negatively affect performance on clean, unperturbed data. We developed a fusion model using a combination of background and foreground features extracted in parallel from Places-CNN and Imagenet-CNN. We tested the benefits of the fusion approach on preserving adversarial robustness for human perceivable (e.g., Gaussian blur) and network perceivable (e.g., gradient-based) attacks for CIFAR-10 and MS COCO data sets. For gradient based attacks, our results show that fusion allows for significant improvements in classification without decreasing performance on unperturbed data and without need to perform adversarial retraining. Our fused model revealed improvements for Gaussian blur type perturbations as well. The increase in performance from fusion approach depended on the variability of the image contexts; larger increases were seen for classes of images with larger differences in their contexts. We also demonstrate the effect of regularization to bias the classifier decision in the presence of a known adversary. We propose that this biologically inspired approach to integrate information across multiple modalities provides a new way to improve adversarial robustness that can be complementary to current state of the art approaches.

图像修补是图像处理任务中的一项关键技术,它能预测图像中的缺失区域,生成逼真的图像。考虑到具有特征提取、传播和重建能力的现有生成修复模型的进步,在更深层中缺乏高质量的特征提取和转移机制来解决所生成的修复区域上的持续像差。我们的方法,V-LinkNet,开发了高层次的特征转移到深层次的纹理背景的修补区域,我们的工作,提出了一种新的技术相结合的编码器学习通过递归残差过渡层(RSTL)。RSTL层通过直接通信增加唯一的语义信息,很容易适应双编码器。通过将双编码器结构与上下文特征表示损失函数相结合,我们的系统获得了使用高级特征进行修补的能力。为了减少随机mask-image配对的偏差,我们在CelebA-HQ,Paris Street View和Places 2数据集的测试集上引入了一个标准的mask-image配对协议。我们的结果表明,V-LinkNet使用此标准协议在CelebA-HQ和巴黎街景上表现更好。在接受本文后,我们将与研究界分享标准协议和我们的代码。
