A Unified Total Variation Framework for Membrane Potential Perturbation Dynamic

Zhao-Rong Lai, Xiwen Yuan, Ziliang Chen, Liangda Fang, Yongsen Zheng

ICLR 2026poster

Membrane potential perturbation dynamic (MPPD) is an emerging approach to capture perturbation intensity and stabilize the performance of spiking neural networks (SNN). It discards the neuronal reset part to intuitively reduce fluctuations of dynamics, but this treatment may be insufficient in pertu…

Adversarial Attack and Defense for Denoising Diffusion Sampling

Zhao-Rong Lai, Xiwen Yuan, Jian Weng

ICML 2026poster

Denoising diffusion sampling (DDS) is an emerging approach for generating new samples that have the same distribution as some training samples. However, it is vulnerable to adversarial attacks by even a Gaussian perturbation. In this work, we propose a complete set of adversarial attack and defense …
