  1. Disentangling Interaction and Bias Effects in Opinion Dynamics of Large Language Models

    A new Bayesian framework has been developed to disentangle interaction and bias effects in large language models simulating human opinion dynamics. The framework quantifies topic, agreement, and anchoring biases, finding that while opinion trajectories converge over time, biases differ across LLMs. The study also demonstrates that fine-tuning LLMs on opinionated statements can shift their default stances, highlighting both the potential and limitations of using LLMs as proxies for human behavior.

    IMPACT Provides a quantitative tool to understand and compare biases in LLM-driven opinion dynamics, crucial for reliable simulation of human behavior.

  2. Learning Through Noise: Why Subliminal Learning Works and When It Fails

    Researchers have demonstrated that subliminal learning in neural networks, where knowledge is transferred via task-unrelated data, is primarily governed by compatible output heads rather than shared model initialization. By splitting outputs into auxiliary and class heads, they showed that compatible auxiliary heads facilitate the transfer of teacher signals, improving student model representations. This mechanism allows students trained on noise to achieve performance comparable to teachers, providing a theoretically grounded understanding of subliminal learning and its limitations. AI

    IMPACT Explains a novel mechanism for knowledge transfer in neural networks, potentially improving training efficiency and model performance.
