  • Foundations of Safe Online Reinforcement Learning in the Linear Quadratic Regulator: $sqrt{T}$-Regret

    Foundations of Safe Online Reinforcement Learning in the Linear Quadratic Regulator: $sqrt{T}$-Regret arXiv:2504.18657v1 Announce Type: new Abstract: Understanding how to efficiently learn while adhering to safety constraints is essential for using online reinforcement learning in practical applications. However, proving rigorous regret bounds for safety-constrained reinforcement learning is difficult due to the complex interaction between safety,…

  • Fundamental Safety-Capability Trade-offs in Fine-tuning Large Language Models

    Fundamental Safety-Capability Trade-offs in Fine-tuning Large Language Models arXiv:2503.20807v1 Announce Type: new Abstract: Fine-tuning Large Language Models (LLMs) on some task-specific datasets has been a primary use of LLMs. However, it has been empirically observed that this approach to enhancing capability inevitably compromises safety, a phenomenon also known as the safety-capability trade-off in LLM fine-tuning.…

  • Probabilistic Shielding for Safe Reinforcement Learning

    Probabilistic Shielding for Safe Reinforcement Learning arXiv:2503.07671v1 Announce Type: new Abstract: In real-life scenarios, a Reinforcement Learning (RL) agent aiming to maximise their reward, must often also behave in a safe manner, including at training time. Thus, much attention in recent years has been given to Safe RL, where an agent aims to learn an…
