Attribution-Guided Decoding

ICLR 2026poster

The capacity of Large Language Models (LLMs) to follow complex instructions and generate factually accurate text is critical for their real-world application. However, standard decoding methods often fail to robustly satisfy these requirements, while existing control techniques frequently degrade ge…

The Atlas of In-Context Learning: How Attention Heads Shape In-Context Retrieval Augmentation

NeurIPS 2025poster

Large language models are able to exploit in-context learning to access external knowledge beyond their training data through retrieval-augmentation. While promising, its inner workings remain unclear. In this work, we shed light on the mechanism of in-context retrieval augmentation for question ans…

AttnLRP: Attention-Aware Layer-Wise Relevance Propagation for Transformers

ICML 2024poster

Large Language Models are prone to biased predictions and hallucinations, underlining the paramount importance of understanding their model-internal reasoning process. However, achieving faithful attributions for the entirety of a black-box transformer model and maintaining computational efficiency…
