Ensuring that AI operates reliably, predictably, and ethically is crucial for fostering trust and maximizing the benefits of this technology. This section highlights five recent papers that address various aspects of AI safety, focusing on reinforcement learning, reasoning models, and flight testing.

1. Predictive Safety Shield for Dyna-Q Reinforcement Learning

This paper, published on November 26, 2025, introduces a predictive safety shield for Dyna-Q Reinforcement Learning (RL). The proposed shield acts as a safety net, preventing the RL agent from taking actions that could lead to unsafe states. Dyna-Q is a popular RL algorithm that combines model-based and model-free learning techniques. The predictive safety shield enhances the safety of Dyna-Q by predicting the potential consequences of actions and intervening when necessary. This is particularly important in applications where safety is critical, such as robotics, autonomous driving, and healthcare. The shield uses a predictive model to estimate the future state of the environment and compares it to a set of predefined safety constraints. If an action is predicted to violate these constraints, the shield intervenes and selects a safer alternative. This approach allows the RL agent to explore the environment more confidently, knowing that it is protected from potentially harmful outcomes. The development of such safety mechanisms is essential for the widespread adoption of RL in real-world applications.

Self-Guided Defense addresses this issue by providing the model with a set of guidelines that promote safe and ethical reasoning. These guidelines are synthesized automatically, allowing the model to adapt to different contexts and scenarios. The model uses these guidelines to evaluate its own reasoning process and adjust its behavior accordingly. This adaptive alignment mechanism helps to ensure that the model's outputs are aligned with human values and societal norms. This research is crucial for building trustworthy AI systems that can be deployed in sensitive applications, such as healthcare, finance, and law.
