WebA Bayesian network is a graphical model that encodes probabilistic relationships among variables of interest. When used in conjunction with statistical techniques, the graphical model has several advantages for data analysis. One, because the model encodes dependencies among all variables, it readily handles situations where some data entries …

They are also a foundational tool in formulating many machine learning problems. This course is the first in a sequence of three. Webencode the assumptions in a Bayesian network. Bayesian: all models are a stochastic variable, the network with maximum posterior probability. Bayesian approach is more popular: Probability: it provides the probability of a model. Model averaging: predictions can use all models and weight them with their probabilities. HST 951
