Recent studies explore using linear temporal logic (LTL) for ensuring learned controllers comply with safety and reliability requirements in reinforcement learning for real-world applications.
Challenges in traditional safety assurance approaches have led to advocating the use of LTL to derive correct learning objectives from specified requirements.
A new method has been proposed to integrate LTL with differentiable simulators, allowing for efficient learning directly from LTL specifications through soft labeling for differentiable rewards and states.
Experiments validate the proposed method, showing significant improvements in reward attainment and training time compared to discrete methods.
