RFR: Continual Few-shot Reinforcement Learning

RFR: Continual Few-shot Reinforcement Learning

Proposed by Cerenaut and the Whole Brain Architecture Initiative
(What is a Request for Research/RFR?)

This project takes a different approach to RL, inspired by evidence that hippocampus replays to the frontal cortex directly [1, 2, 3].  It is likely used for model building, as opposed to the mainstream view in cognitive science and ML — where ‘experience replay’ ultimately improves policy.  The predicted benefits are sample efficiency, better ability to generalize to new tasks and an ability to learn new tasks without forgetting old ones.  The project objective is to improve biological models and advance state-of-the-art in continual reinforcement learning.

Required Knowledge:
Machine Learning, Deep Learning or some knowledge and willingness to learn. Must have Python and some experience with PyTorch or Tensorflow.
