The paper introduces FATE, a new formal algebra benchmark series spanning from undergraduate exercises to PhD-level research problems, which reveals that current state-of-the-art LLMs struggle significantly with formalizing advanced mathematical reasoning, achieving near-zero accuracy on the most difficult tasks despite stronger natural-language performance.
This paper introduces "Jr. AI Scientist," an autonomous system that mimics a novice researcher's workflow to generate novel, scientifically valuable papers building on real academic works, while simultaneously evaluating its performance through rigorous automated and human assessments to identify both its capabilities and the significant risks and limitations of current AI-driven scientific exploration.
The paper proposes Distributionally Robust Self-Paced Curriculum Reinforcement Learning (DR-SPCRL), a method that adaptively schedules the robustness budget as a continuous curriculum to overcome the performance-robustness trade-off inherent in fixed-budget approaches, thereby achieving superior stability and an 11.8% improvement in episodic return under perturbations compared to existing strategies.
