Recurrent neural policies exhibit limit cycle structures

Researchers have identified stable cyclic structures within the hidden states of recurrent neural policies, drawing parallels to limit cycles in dynamical systems. These emergent cycles appear to stabilize internal memory and relevant environmental states while suppressing noise. The geometry of these limit cycles also correlates with policy behaviors, potentially explaining enhanced generalization and robustness in tasks involving partial observability and meta-reinforcement learning.
