Progress Constraints for Reinforcement Learning in Behavior Trees

Finn Rietz, Mart Kartašev, Petter Ögren +1

Behavior Trees (BTs) provide a structured and reactive framework for decision-making, commonly used to switch between sub-controllers based on environmental conditions. Reinforceme…

Prompt Tuning Decision Transformers with Structured and Scalable Bandits

Finn Rietz, Oleg Smirnov, Sara Karimi +1

Prompt tuning has emerged as a key technique for adapting large pre-trained Decision Transformers (DTs) in offline Reinforcement Learning (RL), particularly in multi-task and few-s…

Prompt-Tuning Bandits: Enabling Few-Shot Generalization for Efficient Multi-Task Offline RL

Finn Rietz, Oleg Smirnov, Sara Karimi +1

Prompting has emerged as the dominant paradigm for adapting large, pre-trained transformer-based models to downstream tasks. The Prompting Decision Transformer (PDT) enables large-…
