Computational rationality: A converging paradigm for intelligence in brains, minds, and machines
After growing up together, and mostly growing apart in the second half of the 20th century,
the fields of artificial intelligence (AI), cognitive science, and neuroscience are reconverging …

A tutorial on Bayesian nonparametric models
SJ Gershman, DM Blei - Journal of Mathematical Psychology, 2012 - Elsevier
A key problem in statistical modeling is model selection, that is, how to choose a model at an
appropriate level of complexity. This problem appears in many settings, most prominently in …

The successor representation: its computational logic and neural substrates
SJ Gershman - Journal of Neuroscience, 2018 - Soc Neuroscience
Reinforcement learning is the process by which an agent learns to predict long-term future
reward. We now understand a great deal about the brain's reinforcement learning algorithms, …

Building machines that learn and think like people
Recent progress in artificial intelligence has renewed interest in building systems that learn
and think like people. Many advances have come from using deep neural networks trained …

The hippocampus as a predictive map
A cognitive map has long been the dominant metaphor for hippocampal function, embracing
the idea that place cells encode a geometric representation of space. However, evidence …

The successor representation in human reinforcement learning
Theories of reward learning in neuroscience have focused on two families of algorithms
thought to capture deliberative versus habitual choice. ‘Model-based’ algorithms compute the …
