Explaining Generalization Power of a DNN Using Interactive Concepts

no code implementations25 Feb 2023 Huilin Zhou, Hao Zhang, Huiqi Deng, Dongrui Liu, Wen Shen, Shih-Han Chan, Quanshi Zhang

Although there is no universally accepted definition of the concepts encoded by a DNN, the sparsity of interactions in a DNN has been proved, i. e., the output score of a DNN can be well explained by a small number of interactions between input variables.

BadDet: Backdoor Attacks on Object Detection

1 code implementation28 May 2022 Shih-Han Chan, Yinpeng Dong, Jun Zhu, Xiaolu Zhang, Jun Zhou

We propose four kinds of backdoor attacks for object detection task: 1) Object Generation Attack: a trigger can falsely generate an object of the target class; 2) Regional Misclassification Attack: a trigger can change the prediction of a surrounding object to the target class; 3) Global Misclassification Attack: a single trigger can change the predictions of all objects in an image to the target class; and 4) Object Disappearance Attack: a trigger can make the detector fail to detect the object of the target class.

Towards Theoretical Analysis of Transformation Complexity of ReLU DNNs

1 code implementation4 May 2022 Jie Ren, Mingjie Li, Meng Zhou, Shih-Han Chan, Quanshi Zhang

Based on the proposed metrics, we analyze two typical phenomena of the change of the transformation complexity during the training process, and explore the ceiling of a DNN's complexity.
