Shannon‟s definition of information bayesian

WebbEfforts to quantify information have been in agreement that it depends on probabilities (through Shannon entropy), but there has long been a dispute about the definition of probabilities themselves. The frequentist view is that probabilities are (or can be) essentially equivalent to frequencies, and that they are therefore properties of a physical … WebbIn work in collaboration with Prof. Pierre Baldi at the University of California at Irvine, we have developed a formal Bayesian definition of surprise that is the only consistent …

The prior represents your knowledge of the parameters before seeing data. The likelihood is the probability of the data given values of the parameters. The posterior is the probability of the parameters given the data. Bayes’ theorem relates the prior, likelihood, and posterior distributions.
