Is Batchnorm a Good Machine Learning Tool?

Bachnorm normalizes the activagiens coming out of a particular unit, or particular convolution. But it also multiplies them by a trainable scale parometer and adds a trainable perometer. Every time you use batchnorm, you're introducing two new tranable perometers per feature. And they're often so neglected that when i was trying to run a completely different experiment, i wanted to freeze the weights in the network, and i forgot to freeze the batchnorm weights because i forgot they existed. It's kind of a fun idea and an interesting piece of science.
