1. 1That the energy cannot increase under the deterministic Hopfield dynamics is a consequence of the fact that the diagonal weights are set to zero.

7. 7Nesterov`s accelerated gradient scheme is often more efficient than the simple momentum scheme because the weighting factor of the momentum term increases as a function of iteration number.

10. 10Different layers of a deep network learn at different speeds because their effects on the output are different.
