Poisoning MorphNet for Clean-Label Backdoor Attack to Point Clouds

no code implementations11 May 2021 Guiyu Tian, Wenhao Jiang, Wei Liu, Yadong Mu

To this end, MorphNet jointly optimizes two objectives for sample-adaptive poisoning: a reconstruction loss that preserves the visual similarity between benign / poisoned point clouds, and a classification loss that enforces a modern recognition model of point clouds tends to mis-classify the poisoned sample to a pre-specified target category.

Fast Non-Local Neural Networks with Spectral Residual Learning

1 code implementation MM '19: Proceedings of the 27th ACM International Conference on Multimedia 2019 Lu Chi, Guiyu Tian, Yadong Mu, Lingxi Xie, Qi Tian

We show its equivalence to conducting residual learning in some spectral domain and carefully re-formulate a variety of neural layers into their spectral forms, such as ReLU or convolutions.

Two-Stream Video Classification with Cross-Modality Attention

no code implementations1 Aug 2019 Lu Chi, Guiyu Tian, Yadong Mu, Qi Tian

In the experiments, we comprehensively compare our method with two-stream and non-local models widely used in video classification.
