We study lifelong reinforcement learning (RL) in a regret minimization setting of linear contextual Markov decision process (MDP), where the agent needs to learn a multi-task policy while solving a streaming sequence of tasks. We propose an algorithm, called UCB Lifelong Value Distillation (UCBlvd), that provably achieves sublinear regret for any sequence of tasks, which may be adaptively chosen based on the agent’s past behaviors. Remarkably, our algorithm uses only sublinear number of…

A novel metric between Markov Decision Processes is introduced and established that close MDPs have close optimal value functions, which lead to a value transfer method for Lifelong RL, which is used to build a PAC-MDP algorithm with improved convergence rate.
