arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • A new study introduces Sharpness-Aware Minimization (SAM) as a solution to enhance the robustness of offline reinforcement learning (RL) against data corruption, which has been a significant challenge for existing algorithms. The research demonstrates that SAM can guide models towards flatter minima in the loss landscape, improving generalization and performance in the presence of corrupt data. The integration of SAM with established algorithms like IQL and RIQL shows promising results on D4RL benchmarks.
  • This development is crucial as it addresses the vulnerabilities of offline RL algorithms, which often struggle with real-world data corruption. By utilizing SAM, researchers can potentially improve the reliability and effectiveness of RL applications in various fields, including robotics and autonomous systems, where data integrity is paramount for successful learning and decision-making.
  • The application of SAM not only highlights the importance of optimization techniques in machine learning but also aligns with ongoing discussions about the stability and efficiency of different optimization methods. As the field evolves, the exploration of SAM alongside other frameworks, such as those utilizing large language models for reward optimization, underscores a growing trend towards enhancing learning robustness and adaptability in AI systems.

Efficiently Seeking Flat Minima for Better Generalization in Fine-Tuning Large Language Models and Beyond
PositiveArtificial Intelligence
Recent research has introduced Flat Minima LoRA (FMLoRA) and its efficient variant EFMLoRA, aimed at enhancing the generalization of large language models by seeking flat minima in low-rank adaptation (LoRA). This approach theoretically demonstrates that perturbations in the full parameter space can be effectively transferred to the low-rank subspace, minimizing interference from multiple matrices.
