Investigating Social Bias Propagation in Federated Fine-tuning of Large Language Models

AAAI 2026technical

Large language models (LLMs) have achieved remarkable success in many domains, but concerns about data quality and privacy are growing. Federated Learning (FL) offers a privacy-preserving solution by training a model on local clients without sharing data. However, the impact of biased private data o

Understanding Large Language Model Vulnerabilities to Social Bias Attacks

ACL 2025long

Large Language Models (LLMs) have become foundational in human-computer interaction, demonstrating remarkable linguistic capabilities across various tasks. However, there is a growing concern about their potential to perpetuate social biases present in their training data. In this paper, we comprehe…

Unmasking Style Sensitivity: A Causal Analysis of Bias Evaluation Instability in Large Language Models

ACL 2025long

Natural language processing applications are increasingly prevalent, but social biases in their outputs remain a critical challenge. While various bias evaluation methods have been proposed, these assessments show unexpected instability when input texts undergo minor stylistic changes. This paper co…

CHAmbi: A New Benchmark on Chinese Ambiguity Challenges for Large Language Models

EMNLP 2024finding

Ambiguity is an inherent feature of language, whose management is crucial for effective communication and collaboration. This is particularly true for Chinese, a language with extensive lexical-morphemic ambiguity. Despite the wide use of large language models (LLMs) in numerous domains and their gr…

More than Minorities and Majorities: Understanding Multilateral Bias in Language Generation

ACL 2024findings

Pretrained models learned from real corpora can often capture undesirable features, leading to bias issues against different demographic groups. Most existing studies on bias dataset construction or bias mitigation methods only focus on one demographic group pair to study a certain bias, e.g. black…
