Researchers have introduced SmoothFBO, a novel algorithm designed to address non-stationary functional bilevel optimization (FBO) problems. Unlike previous methods confined to static settings, SmoothFBO offers theoretical guarantees and practical scalability for dynamic environments. The algorithm employs a time-smoothed stochastic hypergradient estimator to stabilize updates and reduce variance, making it applicable to both classical parametric bilevel optimization and more complex online scenarios. Empirical results show SmoothFBO outperforming existing FBO techniques in hyperparameter optimization and model-based reinforcement learning. AI
