AsyncTLS: Efficient Generative LLM Inference with Asynchronous Two-level Sparse Attention

Yuxuan Hu, Jianchao Tan, Jiaqi Zhang +7

Long-context inference in LLMs faces the dual challenges of quadratic attention complexity and prohibitive KV cache memory. While token-level sparse attention offers superior accur…

Sparse-RL: Breaking the Memory Wall in LLM Reinforcement Learning via Stable Sparse Rollouts

Sijia Luo, Xiaokang Zhang, Yuxuan Hu +6

Reinforcement Learning (RL) has become essential for eliciting complex reasoning capabilities in Large Language Models (LLMs). However, the substantial memory overhead of storing K…

TableCache: Primary Foreign Key Guided KV Cache Precomputation for Low Latency Text-to-SQL

Jinbo Su, Yuxuan Hu, Cuiping Li +4

In Text-to-SQL tasks, existing LLM-based methods often include extensive database schemas in prompts, leading to long context lengths and increased prefilling latency. While user q…

Optimizing Native Sparse Attention with Latent Attention and Local Global Alternating Strategies

Yuxuan Hu, Jianchao Tan, Jiaqi Zhang +7

In this work, we conduct a systematic analysis of Native Sparse Attention (NSA) and propose targeted improvements that enhance long-context modeling. A key insight is that alternat…

QUAD: Quantization and Parameter-Efficient Tuning of LLM with Activation Decomposition

Yuxuan Hu, Xiaodong Chen, Cuiping Li +2

Large Language Models (LLMs) excel in diverse applications but suffer inefficiency due to massive scale. While quantization reduces computational costs, existing methods degrade ac…
