Boosting the Transferability of Adversarial Examples via Local Mixup and Adaptive Step Size

ICASSP 2025accepted

Adversarial examples are one critical security threat to various visual applications, where injected human-imperceptible perturbations confuse the output. Generating transferable adversarial examples in the black-box setting is crucial but challenging in practice. Existing input-diversity-based meth…

SDNET: Lightweight Facial Expression Recognition For Sample Disequilibrium

ICASSP 2022accepted

Facial expression recognition (FER) based on the convolutional neural network (CNN) in the wild have numerous challenges. For instance, the complexity of the network model makes FER tasks difficult to deploy on portable devices. Some approaches design lightweight networks to reduce the model size, w…
