LESA: Learnable Stage-Aware Predictors for Diffusion Model Acceleration

CVPR 2026

Diffusion models have achieved remarkable success in image and video generation tasks. However, the high computational demands of Diffusion Transformers (DiTs) pose a significant challenge to their practical deployment. While feature caching is a promising acceleration strategy, existing methods bas

When Agents Go Rogue: Activation-Based Detection of Malicious Behaviors in Multi-Agent Systems

ICML 2026poster

While enabling effective collaboration on complex tasks, LLM-based Multi-Agent Systems (MAS) face critical security challenges due to vulnerabilities at the agent and interaction levels. Most existing MAS security defenses are built upon two core assumptions: semantically-explicit malicious attacks …

AutoLoss: Learning Discrete Schedule for Alternate Optimization

ICLR 2019poster

Many machine learning problems involve iteratively and alternately optimizing different task objectives with respect to different sets of parameters. Appropriately scheduling the optimization of a task objective or a set of parameters is usually crucial to the quality of convergence. In this paper,…
