Entropy-Preserving Reinforcement Learning

This paper argues that standard policy gradient algorithms inadvertently reduce trajectory diversity by lowering entropy during training, and proposes new entropy-preserving methods like REPO and ADAPO to actively control entropy, thereby maintaining diversity and improving both final performance and the capacity for sequential learning.

Scaling Laws for Educational AI Agents

This paper introduces the "Agent Scaling Law" and the AgentProfile framework to demonstrate that the capabilities of educational AI agents scale predictably with structured profile richness—specifically role clarity, skill depth, tool completeness, runtime capability, and educator expertise—rather than solely through increased model size, as validated by the EduClaw platform's deployment of over 330 agent profiles.

Gender Bias in Generative AI-assisted Recruitment Processes

This study evaluates the potential for gender bias in generative AI-assisted recruitment by analyzing how a state-of-the-art model (GPT-5) suggests occupations for simulated Italian graduates, revealing that while job recommendations remain neutral, the model perpetuates gender stereotypes by attributing emotional traits to women and analytical traits to men.
