On The Role of Approximations in Bayesian Cognitive Science
The Bayesian framework is prominent in contemporary cognitive science. Its key tenet is that many aspects of cognition can be modeled as a one form or another of Bayesian inference. Early work within the framework applied this idea in a fairly direct manner. But, due to considerations of tractability and explanatory power, more recent work has appealed to approximations – such as Monte Carlo simulations and related methods. Consequently, Bayesian cognitive scientists now tend to speak of the mind as “approximating Bayesian inference”. My talk will discuss such claims and their justification. I will suggest that the idea the mind approximates Bayes lacks a straightforward interpretation. This situation affects the big picture coming out of Bayesian work, as well as the rationale behind its top-down methodology.
