WebOct 6, 2024 · The CNN will still output classifications having been tricked by something with a resemblance to human face. CNNs cry out for the Bayesian treatment, because we don’t want our work undermined by silly mistakes and because where the consequences of misclassification are high we want to know how sure the network is. 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 …
