You can, by the way, get documentation about network2.

It is, of course, nice that we see such improvements. But the interpretation of such improvements is always problematic. The example involves a neuron with just one input: This is usually true in classification problems, but for other problems e. Does this problem afflict the first expression?

You may wish to revisit that chapter if you need to refresh your memory about the meaning of the notation. By contrast, we learn more slowly when our errors are less well-defined.

The challenge is to understand why they are small. We get low surprise if the output is what we expect, and high surprise if the output is unexpected.

Why or why not? Why is learning so slow? You might object that the change in learning rate makes the graphs above meaningless. And the details can be filled in by working through the materials about the Kraft inequality in chapter 5 of the book about information theory by Cover and Thomas.

The larger the error, the faster the neuron will learn.

To see this, notice that: Two properties in particular make it reasonable to interpret the cross-entropy as a cost function. If this is not obvious to you, then you should work through that analysis as well. There is, incidentally, a very rough general heuristic for relating the learning rate for the cross-entropy and the quadratic cost.

Where does it come from? This behaviour is strange when contrasted to human learning. For both cost functions I simply experimented to find a learning rate that made it possible to see what is going on. When should we use the cross-entropy instead of the quadratic cost?

That objection misses the point. In this chapter I explain a suite of techniques which can be used to improve on our vanilla implementation of backpropagation, and so improve the way our networks learn. SGD in a Python shell.

You can bet that the next time I played before an audience I played in the correct octave! In this case the quadratic cost is, in fact, an appropriate cost function to use.• Unit cost rates in calculations, but doesn't determine those rates.
