Research Meeting: Modular learning and reasoning on ARC

Abstract: Current machine learning algorithms are highly specialized to whatever it is they are meant to do — e.g. playing chess, picking up objects, or object recognition. How can we extend this to a system that could solve a wide range of problems? We argue that this can be achieved by a modular system — one that can adapt to solving different problems by changing only the modules chosen and the order in which those modules are applied to the problem. The recently introduced ARC (Abstraction and Reasoning Corpus) dataset serves as an excellent test of abstract reasoning. Suited to the modular approach, the tasks depend on a set of human Core Knowledge inbuilt priors. We implement these priors as the modules of a reasoning system and combine them using neural-guided program synthesis. We then discuss our ongoing efforts extending execution-guided program synthesis to a bidirectional search algorithm via function inverse semantics.​
