Replay in the brain has been viewed as rehearsal, or, more recently, as sampling from a transition model.

There has been rapidly growing interest in meta-learning as a method for increasing the flexibility and sample efficiency of reinforcement learning.
The emergence of powerful artificial intelligence is defining new research directions in neuroscience.

In this report we review memory-based meta-learning as a tool for building sample-efficient strategies that learn from past experience to adapt to any task within a target class.
Discovering and exploiting the causal structure in the environment is a crucial challenge for intelligent agents.
Meta-learning agents excel at rapidly learning new tasks from open-ended task distributions; yet, they forget what they learn about each task as soon as the next begins.
We unpack these points in a series of seven proof-of-concept experiments, each of which examines a key aspect of deep meta-RL.
