Detecting Backdoor Attacks in Federated Learning via Direction Alignment Inspection

CVPR 2025highlight

The distributed nature of training makes Federated Learning (FL) vulnerable to backdoor attacks, where malicious model updates aim to compromise the global model's performance on specific tasks. Existing defense methods show limited efficacy as they overlook the inconsistency between benign and mali…

FlowerTune: A Cross-Domain Benchmark for Federated Fine-Tuning of Large Language Models

NeurIPS 2025poster

Large Language Models (LLMs) have achieved state-of-the-art results across diverse domains, yet their development remains reliant on vast amounts of publicly available data, raising concerns about data scarcity and the lack of access to domain-specific, sensitive information. Federated Learning (FL)…

Distractor-Aware Fast Tracking via Dynamic Convolutions and MOT Philosophy

CVPR 2021poster

A practical long-term tracker typically contains three key properties, i.e., an efficient model design, an effective global re-detection strategy and a robust distractor awareness mechanism. However, most state-of-the-art long-term trackers (e.g., Pseudo and re-detecting based ones) do not take all…
