Chapter 6 of the book says:
“note: Getting Model Activations: Knowing how to manually get a mini-batch and pass it into a model, and look at the activations and loss, is really important for debugging your model. It is also very helpful for learning, so that you can see exactly what is going on.”
Q. Why is passing a mini-batch to a model “really important for debugging”? Would you describe some production examples to show this?
