“Throw away” --> set activation to zero? (Or to NaN, null, undefined… and handle it in some special way?)

What does dropping a unit mean? Set it’s activation to 0? What happens in the back propagation step? Does the unit get it’s weights updated?

If you drop some of the activations, would their weights get updated at the end of the mini batch?
