The Bayesian approach enables us to apply prior probability distribution, which acts as a regularizer and helps us to address the over-fitting problem when there is less data available. This ability is further complemented by the ResNet architecture. See more To effectively solve the problem of handwritten digit recognition, we propose the implementation of Bayesian ResNet. We apply the Bayesian approach on the ResNet-18 architecture [21]. Firstly, we will discuss the … See more To solve the problem discussed in the above section, Graves et al. [18] advised that the Bayesian posterior distribution on the weights can be … See more To include Bayesian inference, we need to treat the weights of our neural network as a probability distribution rather than a single point estimate.
