  This paper addresses the scalability problem of Bayesian deep neural
networks. The performance of deep neural networks is undermined by the fact
that these algorithms have poorly calibrated measures of uncertainty. This
restricts their application in high risk domains such as computer aided
diagnosis and autonomous vehicle navigation. Bayesian Deep Learning (BDL)
offers a promising method for representing uncertainty in neural network.
However, BDL requires a separate set of parameters to store the mean and
standard deviation of model weights to learn a distribution. This results in a
prohibitive 2-fold increase in the number of model parameters. To address this
problem we present a method for performing BDL, namely Kernel Seed Networks
(KSN), which does not require a 2-fold increase in the number of parameters.
KSNs use 1x1 Convolution operations to learn a compressed latent space
representation of the parameter distribution. In this paper we show how this
allows KSNs to outperform conventional BDL methods while reducing the number of
required parameters by up to a factor of 6.6.
