HiFA4: Training-Free 4-bit FlashAttention on Ascend HIF4 NPUs for LLM Inference
Hui Dong, Yanzhao Li, Jie Gao +5
We present HiFA4, a post-training operator-level design that executes both QK^T and PV in FlashAttention as 4-bit HIF4 Cube GEMMs for LLM inference on Ascend NPUs, while maintainin…

Training-free sparse attention based on cumulative energy filtering
Chunlu Li, Yixuan Pan, Bai Du +5
Sparse attention accelerates Diffusion Transformers (DiTs) for video generation by computing only the important tokens while skipping the rest. The token selection strategy is key…

Robust Model-based Face Reconstruction through Weakly-Supervised Outlier Segmentation
Chunlu Li, Andreas Morel-Forster, Thomas Vetter +2
In this work, we aim to enhance model-based face reconstruction by avoiding fitting the model to outliers, i.e. regions that cannot be well-expressed by the model such as occluders…
