📄 Coding Agents for Generalized Task and Motion Planning Problems via arXiv
Task and motion planning (TAMP) problems remain difficult even with full observability and object-centric states because discrete decisions are tightly coupled to geometric, kinematic, and dynamic con

📄 Minimally Invasive Steering of Language Models via arXiv
Pre-logit steering adapts a frozen language model to a test-time reward by adding vectors to its final hidden states. Unregularized reward optimization can substantially alter the output distribution
