Light Forcing: Accelerating Autoregressive Video Diffusion via Sparse Attention

ICML 2026poster

Advanced autoregressive (AR) video generation models have improved visual fidelity and interactivity, but the quadratic complexity of attention remains a primary bottleneck for efficient deployment. While existing sparse attention solutions have shown promise on bidirectional models, we identify tha…

Mind the Cost of Scaffold! Benign Clients May Even Become Accomplices of Backdoor Attack

ICCV 2025poster

By using a control variate to calibrate the local gradient of each client, Scaffold has been widely known as a powerful solution to mitigate the impact of data heterogeneity in Federated Learning. Although Scaffold achieves significant performance improvements, we show that this superiority is at th…
