Macrolearning#

Over the last two weeks in this NeuroAI course, we’ve focused on numerous aspects of learning mechanisms, inductive biases and how generalization is implemented as a fundamental property of successful learning systems. Back in Day 2 we looked at the topic of “Comparing Tasks” and Leila Wehbe introduced the idea of learning at multiple temporal scales. This idea was explored fairly lightly back then, but today we’re going to go much deeper into this idea of learning of a macro-level of time and in a Reinforcement Learning framework. What does it mean about learning across the scale of biological evolution and at the species level? That’s what today is all about. We hope you enjoy this fascinating topic!

Prerequisites#

For this day, it would be beneficial to have prior experience working with the pytorch modeling package, as the last tutorials are going to be concentrated on defining architecture and training rules using this framework. For Tutorials 4 & 5, you might find yourself more comfortable if you are familiar with the reinforcement learning paradigm and with the Actor-Critic model, in particular. Actually, Tutorial 4 will elaborate on the agent already introduced previously in the last tutorial of Day 2, completing the discussion of meta-learning. It might also be useful to revisit the recording in Tutorial 3 of Day 2, specifically related to the idea of Partially-Observable Markov Decision Processes (POMDPs).
