Adopting the scientific methodology into applied machine learning we could start to understand why stuff works — and go beyond the metaphorical explanations which are so common to our field. Also, machine learning predictions as inputs to a non-Bayesian analysis seems reminiscent of Efron and Tibshirani’s pre-validation approach where they, in turn, fit ML for one subset, using date other than in that subset, and the fit additional covariates in each subset and then put all the subsets together completely pool the covariates as.

Gal's paper gives a complete theoretical treatment of the link between Gaussian processes and dropout, and develops the tools necessary to. We show that the combined neural activations of such a hidden layer have class-specific distributional properties, and then define multiple statistical. Gal and Ghahramani (2015) have extended that work showing that by defining the approximating distribution as in eq. Bayesian methods also allow us to estimate uncertainty in predictions, which is a desirable feature for fields like medicine. the problem from a new perspective, formulating it as a supervised learning task under noise labels.
