Speculative Streaming: Efficient and Scalable Speculative Decoding with Multi-Stream Attention

EMNLP 2025

Speculative decoding is a prominent technique for accelerating LLM inference by leveraging an auxiliary draft model, but its effectiveness is limited by the autoregressive nature of draft generation, where acceptance rates depend on the draft model’s size. Scaling the draft model improves acceptance

Superposition Prompting: Improving and Accelerating Retrieval-Augmented Generation

ICML 2024poster

Despite the successes of large language models (LLMs), they exhibit significant drawbacks, particularly when processing long contexts. Their inference cost scales quadratically with respect to sequence length, making it expensive for deployment in some real-world text processing applications, such a…

Deformer: Dynamic Fusion Transformer for Robust Hand Pose Estimation

ICCV 2023poster

Accurately estimating 3D hand pose is crucial for understanding how humans interact with the world. Despite remarkable progress, existing methods often struggle to generate plausible hand poses when the hand is heavily occluded or blurred. In videos, the movements of the hand allow us to observe var…

Domain Adaptive Hand Keypoint and Pixel Localization in the Wild

ECCV 2022poster

"We aim to improve the performance of regressing hand keypoints and segmenting pixel-level hand masks under new imaging conditions (e.g., outdoors) when we only have labeled images taken under very different conditions (e.g., indoors). In the real world, it is important that the model trained for bo…
