Abstract: It is immensely empowering to delegate information processing work to machines and have them carry out difficult tasks on our behalf. But programming computers is hard. The traditional approach to this problem is to try to fix people: They should work harder to learn to code. In this talk, I argue that a promising alternative is to meet people partway. Specifically, powerful new approaches to machine learning provide ways to infer intent from disparate signals and could help make it easier for everyone to get computational help with their vexing problems.

[full title] Efficient representation, learning, and planning through abstraction: clustering cognitive spaces into submaps
Ila Fiete, MIT
Abstract: Episodic memory involves fragmenting the continuous stream of experience into discrete episodes. Not coincidentally, the hippocampus, which plays a central role in both episodic memory and spatial navigation, represents large spatial environments in a fragmented way even when explored in a continuous trajectory. In non-spatial and non-memory contexts too, humans report sudden contextual re-anchoring or re-orientation when reading garden path sentences (“Time flies like an arrow, fruit flies like a banana.) or watching a movie with viewpoint changes. In this talk, I will describe a theory for the online and real-time generation of fragmented representations and contextual re-anchoring from continuous experience that resemble those obtained by principled but offline and computationally complex information-based algorithms. The resulting fragmentations closely match those observed from neural recordings in animals navigating through complex environments. I will discuss the utility of map fragmentation, as a form of state abstraction that enables representation fidelity, flexible and rapid learning through reuse of existing fragments, and many-fold improvements in the ability to plan and navigate through complex environments relative to more global representations.
