Bayesian Computation in Deep Learning

Bayesian computation has achieved profound success in many modeling tasks with statistics tools such as generalized linear models (Dobson and Barnett, 2018; Nelder and Wedderburn, 1972). Yet these traditional tools fail to produce satisfactory predictions for high-dimensional and highly complex data such as images, speech and videos. Deep Learning (LeCun et al., 2015a) provides an attractive solution. At the time of late 2023, deep neural networks achieve accurate predictions for image classification (Dehghani et al., 2023), segmentation (Kirillov et al., 2023) and speech recognition tasks (Zhang et al., 2023). Meanwhile they have also demonstrated an astonishing capability for generating photo-realistic and/or artistic images (Rombach et al., 2022), music (Agostinelli et al., 2023) and videos (Liang et al., 2022). Nowadays deep neural networks have become a standard modeling tool for many of the applications in AI and related fields, and the success of deep learning so far are based on training deterministic deep neural networks on big data. So one might ask: is there a place for Bayesian computation in modern deep learning?
