LongRecipe: Recipe for Efficient Long Context Generalization in Large Language Models

ACL 2025long

Large language models (LLMs) face significant challenges in handling long-context tasks because of their limited effective context window size during pretraining, which restricts their ability to generalize over extended sequences. Meanwhile, extending the context window in LLMs through post-pretrai…

Mitigating Posterior Salience Attenuation in Long-Context LLMs with Positional Contrastive Decoding

ACL 2025short

While Large Language Models (LLMs) support long contexts, they struggle with performance degradation within the context window. Current solutions incur prohibitive training costs, leaving statistical behaviors and cost-effective approaches underexplored. From the decoding perspective, we identify th…
