WebMar 11, 2024 · The conventional (non-Bayesian) way is to learn only the optimal values via maximum likelihood estimation. These values are scalars, like w_1 = 0.8 or b_1 = 3.1 . … WebAug 30, 2024 · In a Bayesian neural network, each weight is probability distribution instead of a fixed value. Each time you feed an input to a Bayesian network, the weight will be slightly different and so you get slightly different output each time, even for the same input.
