By the way, these probabilities are only statements of belief from a classifier.Whether they correspond to real probabilities is another matter completely and it’s called called likelihood of data given model parameters. People often use likelihood for evaluation of models: a model that gives higher likelihood to real data is better. It’s a probability distribution over model parameters obtained from prior beliefs and data.

In this setting you spare no effort to make the best use of available input.Consider deep learning: you can train a network using Adam, RMSProp or a number of other optimizers.However, they tend to be rather similar to each other, all being variants of Stochastic Gradient Descent.As far as classification goes, most classifiers are able to output probabilistic predictions.Even SVMs, which are sort of an antithesis of Bayesian.

In the spectrum of Bayesian methods, there are two main flavours. The latter contains the so-called nonparametric approaches.

  1. Subgroup analyses of mortality among patients randomized to very low protein plus supplements have revealed either no difference in mortality following initiation of renal replacement therapy [14] or an increase in mortality compared to subjects randomized to low protein intake [15].
