Hi all,

Thank you very much for the feedback

One small thing, is there a some sort of accuracy measurement that we can
show for deep networks?

Yes, there is. Usually the accuracy of the deep network is shown with a
validation dataset and a test set (i.e. validation error and test error).
In other words, after training the network, we run an independent test set
and see how accurate the algorithm is (# of correct results/ # of total
results)

It seems the test accuracy would fit for the model comparison
