Detailed Description
Bayesian approaches in computational neuroscience rely on the properties of Bayesian statistics for performing inference over unknown variables given a data set generated through a stochastic process.
Given a set of observed data d 1:n , generated from a stochastic process P(d 1:n |X) where X is a set of unobserved variables, the posterior probability distribution of X is P(X|d 1:n ) = P(d 1:n |X)P(X)/P(d 1:n ) according to Bayes rule. X can be a set of fixed parameters as well as a series of variables of the same size as the data itself X 1:n .
Based on the posterior probability and a specified utility function, an estimate of X can be made that can be shown to be optimal, e.g., by minimizing the expected variance.
One common use of this principle within computational neuroscience is for inferring unobserved properties (hidden variables X) based on observed data, d. These techniques can be used for inference on any data set but has in neuroscience mostly been...
