论文摘要

在本文中,我们提出了一种培训卷积神经网络的策略,以有效解决与整个网络中与类别间信息有关的竞争假设引起的干扰。前提是基于特征绑定的概念,该概念被定义为激活在网络中的空间和网络层的传播的过程成功集成,以得出正确的推理决策。在我们的工作中,这是针对密集图像标记的任务来完成的,通过基于其类标签混合图像,然后训练特征绑定网络,该特征绑定网络同时片段并将混合图像分开。随后的降低噪声激活的特征揭示了其他理想的特性和高度的成功预测。通过此过程,我们揭示了一种与任何先前方法不同的一般机制,用于提高基本分割网络的性能,同时提高对对抗性攻击的鲁棒性。

In this paper, we present a strategy for training convolutional neural networks to effectively resolve interference arising from competing hypotheses relating to inter-categorical information throughout the network. The premise is based on the notion of feature binding, which is defined as the process by which activation's spread across space and layers in the network are successfully integrated to arrive at a correct inference decision. In our work, this is accomplished for the task of dense image labelling by blending images based on their class labels, and then training a feature binding network, which simultaneously segments and separates the blended images. Subsequent feature denoising to suppress noisy activations reveals additional desirable properties and high degrees of successful predictions. Through this process, we reveal a general mechanism, distinct from any prior methods, for boosting the performance of the base segmentation network while simultaneously increasing robustness to adversarial attacks.
