Concepts and Conceptual Leaps

Abstract: 

Ensuring that machine learning models truly understand the concepts that they wish to learn, and are able to make conceptual leaps to generalize to novel concepts is a major problem on the path to human-level AI. In this talk I will describe some of the work we have been doing in Facebook AI Research in pursuit of this problem. We will first describe a novel task, CURI which tests the conceptual leap ability of AI models. We then probe the question of concepts from a more foundational perspective, testing when models truly understand concepts and generalize out of distribution, when they work in a manner that demonstrates an understanding of objects in a scene or important / noteworthy waypoints in reinforcement learning. I will then conclude with thoughts on future work.
