Description

I tried cifar10_bnn example with bayesian_vgg as an example architecture with default hyper-parameters. However, the loss seems to increase and model results are not consistent. I ran the bayesian_neural_network example of MNIST, which works well. Also, I ran a small network and that seems to work as well. I think something wrong in the models implementation of bayesian_vgg or am I missing something.

Research direction

Start with the cifar10_bnn example and its bayesian_vgg architecture, then compare them with the working bayesian_neural_network MNIST example and the reported small network. Investigate why the default hyper-parameters produce increasing loss and inconsistent results; the issue is done when the CIFAR10 example trains consistently.
