Computational rationality: A converging paradigm
... Models of computational rationality are built on a base of inferential processes for perceiving, predicting, learning, and reasoning under uncertainty (1–3). Such inferential processes operate on representations that encode probabilistic dependencies among variables capturing the likelihoods of rele ...
