During the 60s and 70s, AI researchers explored intuitions about intelligence by writing programs that displayed  intelligent behavior. Many good ideas came out from this work  but  programs written by hand were not robust or general.
After the 80s, research  increasingly shifted  to the development of learners
capable of inferring  behavior and  functions from experience and data,
and solvers capable of tackling well-defined but intractable models like SAT,
classical planning, Bayesian networks, and POMDPs. The learning approach has
achieved considerable success but results in black boxes that do not have the
flexibility, transparency, and generality of their model-based counterparts.
Model-based approaches, on the other hand, require models and scalable algorithms.
In this talk, I review developments in AI, discuss  the gap between model-free
learners and model-based solvers, and sketch  some of our own recent research
aimed at closing this gap.
