"WebMar 2, 2024 · Bayesian inference is the learning process of finding (inferring) the posterior distribution over w. This contrasts with trying to find the optimal w using optimization through differentiation, the learning process for frequentists. As we now know, to compute the full posterior we must marginalize over the whole parameter space. " - Psdd bayesian network
