Don't Go Breaking My LLM: The Impact of Pruning Attention Layers on Explanation Faithfulness and Confidence Calibration
arXiv:2606.24970v1 Announce Type: new Abstract: Pruning Large Language Models (LLMs) reduces memory and inference costs by removing parts of the network, producing smaller models that retain most of their accuracy. As attention layers are the most resource-intensive parts of LLMs, pruning them is a promising compression strategy. Prior work shows that up to 33% of attention layers can be pruned with minimal accuracy loss. Nevertheless, the impact of attention pruning on model interpretability, specifically faithfulness and confidence calibration, remains unstudied. To address this gap, we stud
The proliferation of LLMs creates an immediate need for more efficient and interpretable models, making research into pruning attention layers timely.
This research addresses a critical trade-off between LLM efficiency (cost, memory) and interpretability (faithfulness, confidence), impacting the practical deployment and trust in AI systems.
Our understanding of how model compression techniques affect not just performance but also crucial aspects like explainability and calibration in LLMs is enhanced.
