The meta-learning algorithm rst learns the task structure in simulation by training on a wide variety of generated insertion tasks.
Webb14 juli 2024 · Model-Based RL Model-Based Meta-Policy Optimization Model-based RL algorithms generally suffer the problem of model bias. Much work has been done to employ model ensembles to alleviate model-bias, and whereby the agent is able to learn a robust policy that performs well across models.

Webb20 dec. 2024 · Actor-Critic methods are temporal difference (TD) learning methods that represent the policy function independent of the value function. A policy function (or policy) returns a probability distribution over actions that … WebbFor the meta-RL evaluation, we study three algorithms: RL2 [18, 19]: an on-policy meta-RL algorithm that corresponds to training a LSTM network with hidden states maintained across episodes within a task and trained with PPO, model-agnostic meta-learning (MAML) [10, 21]: an on-policy gradient-based meta-RL algorithm that embeds policy gradient …
Webb19 aug. 2024 · Probabilistic embeddings for actor-critic RL (PEARL) is currently one of the leading approaches for multi-MDP adaptation problems. A major drawback of many existing Meta-RL methods, including PEARL, is that they do not explicitly consider the safety of the prior policy when it is exposed to a new task for the very first time.
