Gaussian neural network
WebResearch report. Despite the success of deep learning in many application areas, neural networks lack of predictive uncertainty estimates. Gaussian processes, as a Bayesian non-parametric model provide the uncertainty quantification and full mathematical interpretation. But scabality remains the biggest challenge in Gaussian processes.
