Towards Predictable Feature Attribution: Revisiting and Improving Guided BackPropagation

no code implementations29 Sep 2021 Guanhua Zheng, Jitao Sang, Wang Haonan, Changsheng Xu

Recently, backpropagation(BP)-based feature attribution methods have been widely adopted to interpret the internal mechanisms of convolutional neural networks (CNNs), and expected to be human-understandable (lucidity) and faithful to decision-making processes (fidelity).

MMCGAN: Generative Adversarial Network with Explicit Manifold Prior

no code implementations18 Jun 2020 Guanhua Zheng, Jitao Sang, Changsheng Xu

Since the basic assumption of conventional manifold learning fails in case of sparse and uneven data distribution, we introduce a new target, Minimum Manifold Coding (MMC), for manifold learning to encourage simple and unfolded manifold.

Adaptive Adversarial Logits Pairing

no code implementations25 May 2020 Shangxi Wu, Jitao Sang, Kaiyuan Xu, Guanhua Zheng, Changsheng Xu

Specifically, AALP consists of an adaptive feature optimization module with Guided Dropout to systematically pursue fewer high-contribution features, and an adaptive sample weighting module by setting sample-specific training weights to balance between logits pairing loss and classification loss.

Understanding Deep Learning Generalization by Maximum Entropy

no code implementations ICLR 2018 Guanhua Zheng, Jitao Sang, Changsheng Xu

DNN is then regarded as approximating the feature conditions with multilayer feature learning, and proved to be a recursive solution towards maximum entropy principle.
