UIBDiffusion: Universal Imperceptible Backdoor Attack for Diffusion Models

Published in IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2025

A universal, imperceptible backdoor trigger for diffusion models based on universal adversarial perturbations, achieving high attack success rate while preserving generation quality and evading state-of-the-art backdoor defenses (Elijah, TERD).

CATS: Cascaded Adaptive Tree Speculation for Memory-Limited LLM Inference Acceleration

Published in arXiv preprint (in submission), 2026

A self-speculative decoding structure for memory-limited LLM inference on edge devices, achieving up to 5.08x wall-clock speedup with no degradation in generation quality, outperforming the prior SOTA method by up to 1.45x under edge memory constraints.

LatentSift: Policy-State Filtering for Token-Efficient Verification of Software Engineering Agents

Published in arXiv preprint (in submission), 2026

A token-free, execution-free filter that verifies software engineering agents with the hidden states the policy already produced, cutting total verification tokens by 49.1–62.1% at K=16 while hybrid Best@16 matches or improves on each agent's reference workflow.
