From Softmax to Score: Transformers Can Effectively Implement In-Context Denoising Steps

NeurIPS 2025poster

Transformers have emerged as powerful meta-learners, with growing evidence that they implement learning algorithms within their forward pass. We study this phenomenon in the context of denoising, presenting a unified framework that shows Transformers can implement (a) manifold denoising via Laplacia…

Language Models (Mostly) Know When to Stop Reading

NeurIPS 2025poster

Large language models (LLMs) process entire input contexts indiscriminately, which is inefficient when the information required to answer a query is localized within the context. We present dynamic context cutoff, a novel method enabling LLMs to self-terminate processing upon acquiring sufficient ta…
