FlexLoop: Depth-Elastic Looped Policies for Adaptive Test-Time Computation in Deep RL

Xun Wang, Ruishuo Chen, Yu Chen, Zhuoran Li, Longbo Huang

Post-trains a looped reinforcement-learning policy to make useful decisions at several recurrent depths. Combines its original objective with distillation between neighboring depths, then uses agreement across depths to decide when to stop.
