Researchers have introduced Q-ALIGN DT, a novel framework designed to enhance Conditioned Sequence Models (CSMs) by aligning return-to-go (RTG) inputs with the actual performance of learned policies. This method utilizes a Q-function to guide CSMs, ensuring that higher RTGs correspond to trajectories with better expected returns. Experiments on the D4RL benchmark demonstrate that Q-ALIGN DT offers superior controllability and performance, effectively learning structured policies that generalize to complex tasks like velocity-tracking, where previous approaches have faltered.
