Study Examines Trustworthiness Implications of Low-Rank Compression in Large Language Models
An extensive study investigates the effects of low-rank factorization on the reliability of large language models (LLMs) concerning privacy, ethical considerations, adversarial resilience, and fairness. The researchers assessed multiple LLMs that underwent compression through various low-rank factorization techniques. Their findings indicate that while privacy features remain intact, other trust-related attributes may be altered. This research represents the inaugural systematic examination of trustworthiness in compressed LLMs, filling a significant void as model compression becomes essential for deployment in resource-limited environments. Additionally, the study offers an analysis focused on explainability, exploring the internal mechanisms that influence trust-related variations. The paper, identified as arXiv:2511.22099v3, underscores the implications for AI developers refining models for practical use.
