DeLS-Spec: Decoupled Long-Short Contexts for Parallel Speculative Drafting

Hong-Kai Zheng, Piji Li

Speculative decoding accelerates LLM inference by drafting multiple tokens and verifying them in parallel. Block-parallel drafters such as DFlash further improve drafting efficienc…

Temporal Guidance for Large Language Models

Hong-Kai Zheng, Piji Li

Contrastive Decoding (CD) enhances the generation quality of large language models (LLMs) but incurs significant additional computational overhead due to the need for an auxiliary…

LSRS: Latent Scale Rejection Sampling for Visual Autoregressive Modeling

Hong-Kai Zheng, Piji Li

Visual Autoregressive (VAR) modeling approach for image generation proposes autoregressive processing across hierarchical scales, decoding multiple tokens per scale in parallel. Th…
