Accelerated Test-Time Scaling with Model-Free Speculative Sampling

EMNLP 2025

Language models have demonstrated remarkable capabilities in reasoning tasks through test-time scaling techniques like best-of-N sampling and tree search. However, these approaches often demand substantial computational resources, creating a critical trade-off between performance and efficiency. We

Compress, Gather, and Recompute: REFORMing Long-Context Processing in Transformers

NeurIPS 2025poster

As large language models increasingly gain popularity in real-world applications, processing extremely long contexts, often exceeding the model’s pre-trained context limits, has emerged as a critical challenge. While existing approaches to efficient long-context processing show promise, recurrent co…

Mamba Drafters for Speculative Decoding

EMNLP 2025

Speculative decoding has emerged as a promising approach to accelerating large language model (LLM) generation using a fast drafter while maintaining alignment with the target model’s distribution. However, existing approaches face a trade-off: external drafters offer flexibility but can suffer from

Think Clearly: Improving Reasoning via Redundant Token Pruning

EMNLP 2025

Recent large language models have shown promising capabilities in long-form reasoning, following structured chains of thought before arriving at a final answer. However, we observe that these reasoning paths tend to include substantial redundancy; analyzing attention patterns reveals that attention

Hierarchical Context Merging: Better Long Context Understanding for Pre-trained LLMs

ICLR 2024poster

Large language models (LLMs) have shown remarkable performance in various natural language processing tasks. However, a primary constraint they face is the context limit, i.e., the maximum number of tokens they can process. Previous works have explored architectural changes and modifications in posi…
