Probabilistic embeddings for actor-critic rl
Webbbe optimized with off-policy data while the probabilistic encoder is trained with on-policy data. The primary contribution of our work is an off-policy meta-RL algorithm, Probabilistic Embeddings for Actor-critic meta-RL (PEARL). Our method achieves excellent sample efficiency during meta-training, enables fast adaptation by WebbMeta-RL algorithms The most basic algorithm idea we can try is: While training: Sample task \(i\), collect data \(\mathcal{D}_i\) Adapt policy by computing: \(\phi_i = f(\theta, \mathcal{D}_i)\) Collect data \(\mathcal{D}_i^\prime\) using adapted policy \(\pi_{\phi_i}\) Update \(\theta\) according to \(\mathcal{L} (D_i^\prime, \phi_i)\)

WebbIn simulation, we learn the latent structure of the task using probabilistic embeddings for actor-critic RL (PEARL), an off-policy meta-RL algorithm, which embeds each task into a latent space [5]. The meta-learning algorithm rst learns the task structure in simulation by training on a wide variety of generated insertion tasks.
