SparseBalance: Load-Balanced Long Context Training with Dynamic Sparse Attention

Hongtao Xu, Jianchao Tan, Yuxuan Hu +8

While sparse attention mitigates the computational bottleneck of long-context LLM training, its distributed training process exhibits extreme heterogeneity in both \textit{1)} sequ…

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…

Scaling Embeddings Outperforms Scaling Experts in Language Models

Hong Liu, Jiaqi Zhang, Chao Wang +13

While Mixture-of-Experts (MoE) architectures have become the standard for sparsity scaling in large language models, they increasingly face diminishing returns and system-level bot…

Efficient Context Scaling with LongCat ZigZag Attention

Chen Zhang, Yang Bai, Jiahuan Li +19

We introduce LongCat ZigZag Attention (LoZA), which is a sparse attention scheme designed to transform any existing full-attention models into sparse versions with rather limited c…

AFA-LoRA: Enabling Non-Linear Adaptations in LoRA with Activation Function Annealing

Jiacheng Li, Jianchao Tan, Zhidong Yang +4

Low-Rank Adaptation (LoRA) is a widely adopted parameter-efficient fine-tuning (PEFT) method. However, its linear adaptation process limits its expressive power. This means there i…

Accelerate Speculative Decoding with Sparse Computation in Verification

Jikai Wang, Jianchao Tan, Yuxuan Hu +6

Speculative decoding accelerates autoregressive language model inference by verifying multiple draft tokens in parallel. However, the verification stage often becomes the dominant…
