LLM-generated tabular data susceptible to bias propagation, study finds

A new research paper explores how biases present in the input data used for large language models (LLMs) can propagate into synthetic tabular data generated through in-context learning. The study demonstrates that even minor biases in the in-context examples can lead to significant statistical distortions in the generated data. Furthermore, the research highlights a vulnerability where malicious actors could inject bias into synthetic datasets, compromising the fairness of downstream classifiers for specific subgroups. While prompt-side mitigation strategies can reduce these disparities, the inherent sensitivity of LLMs to adversarial prompts remains a challenge. AI

IMPACT Highlights a critical vulnerability in LLM data generation pipelines, potentially impacting fairness in sensitive domains.

    In-Context Bias Propagation in LLM-Based Tabular Data Generation

    arXiv:2506.09630v3 Announce Type: replace Abstract: Large Language Models (LLMs) are increasingly used for synthetic tabular data generation through in-context learning (ICL), offering a practical solution for data augmentation in data scarce scenarios. While prior work has shown…
