In this section, we will provide the basic framework for Bayesian statistical inference. Beyond their value as a general framework for solving problems of induction, Bayesian approaches can make several contributions to the enterprise of modeling human cognition. This tutorial doesn't aim to be a bayesian statistics tutorial - but rather a programming cookbook for those who understand the fundamental of bayesian statistics and want to learn how to build bayesian models using python. If you think Bayes’ theorem is counter-intuitive and Bayesian statistics, which builds upon Baye’s theorem, can be very hard to understand. • Overview of the course. Walsh 2002 As opposed to the point estimators (means, variances) used by classical statis-tics, Bayesian statistics is concerned with generating the posterior distribution of the unknown parameters given both the data and some prior density for these parameters. Roberts, and I discuss the expected improvement approach to Bayesian optimization (with some tweaks/extensions) in this paper.
