One-Step Generative Policies with Q-Learning: A Reformulation of MeanFlow

AAAI 2026technical

We introduce a one-step generative policy for offline reinforcement learning that maps *noise* directly to *actions* via a *residual reformulation* of MeanFlow, making it compatible with Q-learning. While one-step Gaussian policies enable fast inference, they struggle to capture complex, multimodal

Boosting Adversarial Robustness Distillation Via Hybrid Decomposed Knowledge

ICASSP 2024accepted

Adversarial Robust Distillation (ARD) has emerged as a potent defense mechanism tailored to small models against adversarial threats. However, mainstream ARD methods typically exploit teachers’ response as the transferred knowledge, while neglecting the analysis of involved target-related knowledge…

Simple and Effective Stochastic Neural Networks

AAAI 2021technical

Stochastic neural networks (SNNs) are currently topical, with several paradigms being actively investigated including dropout, Bayesian neural networks, variational information bottleneck (VIB) and noise regularized learning. These neural network variants impact several major considerations, includi…

Robust Person Re-Identification by Modelling Feature Uncertainty

ICCV 2019poster

We aim to learn deep person re-identification (ReID) models that are robust against noisy training data. Two types of noise are prevalent in practice: (1) label noise caused by human annotator errors and (2) data outliers caused by person detector errors or occlusion. Both types of noise pose seriou…
