Bilevel Reinforcement Learning via the Development of Hyper-gradient without Lower-Level Convexity
AISTATS 2025poster
Bilevel reinforcement learning (RL), which features intertwined two-level problems, has attracted growing interest recently. The inherent non-convexity of the lower-level RL problem is, however, to be an impediment to developing bilevel optimization methods. By employing the fixed point equation ass…
