Follow the Latent Roadmap: Navigating Revocable Decoding for Diffusion LLMs with Anchor Tokens

Yizhen Yao, Qinglin Zhu, Runcong Zhao +4

The paper introduces Anchor Supervised Revocable Decoding (ASRD), a training‑free method that uses temporally consistent anchor tokens to guide and verify generation in diffusion l…

Steering Frozen LLMs: Adaptive Social Alignment via Online Prompt Routing

Zeyu Zhang, Xiangxiang Dai, Ziyi Han +2

Large language models (LLMs) are typically governed by post-training alignment (e.g., RLHF or DPO), which yields a largely static policy during deployment and inference. However, r…

Semantic Caching for Low-Cost LLM Serving: From Offline Learning to Online Adaptation

Xutong Liu, Baran Atalar, Xiangxiang Dai +5

Large Language Models (LLMs) are revolutionizing how users interact with information systems, yet their high inference cost poses serious scalability and sustainability challenges.…

Faster, Smaller, and Smarter: Task-Aware Expert Merging for Online MoE Inference

Ziyi Han, Xutong Liu, Ruiting Zhou +2

Sparse Mixture of Experts (SMoE) has become a preferred architecture for scaling Transformer capacity without increasing computational cost, as it activates only a small subset of…

A Multi-Agent Conversational Bandit Approach to Online Evaluation and Selection of User-Aligned LLM Responses

Xiangxiang Dai, Yuejin Xie, Maoli Liu +4

Prompt-based offline methods are commonly used to optimize large language model (LLM) responses, but evaluating these responses is computationally intensive and often fails to acco…

Trading Vector Data in Vector Databases

Jin Cheng, Xiangxiang Dai, Ningning Ding +2

Vector data trading is essential for cross-domain learning with vector databases, yet it remains largely unexplored. We study this problem under online learning, where sellers face…
