This is a set of maps that I made for the frontispiece of a bound volume of my mother's journals that she wrote during a sailing trip in the Greek islands. Key ingredients are WARMreader for the route labeling and babel for the place names. Further, I don't know squat about Greek, so I undoubtedly made errors in some of the labels. I'm sending you a one-page excerpt from a paper of mine that was published in the American Journal of Mathematics.

Only gradually do they develop other shots, learning to chip, draw and fade the ball, building on and modifying their basic swing. In a similar way, up to now we've focused on understanding the backpropagation algorithm.

It's our "basic swing", the foundation for learning in most work on neural networks. 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.


The techniques we'll develop in this chapter include: I'll also overview several other techniques in less depth. The discussions are largely independent of one another, and so you may jump ahead if you wish. We'll also implement many of the techniques in running code, and use them to improve the results obtained on the handwriting classification problem studied in Chapter 1.

Of course, we're only covering a few of the many, many techniques which have been developed for use in neural nets. The philosophy is that the best entree to the plethora of available techniques is in-depth study of a few of the most important.

Mastering those important techniques is not just useful in its own right, beautiful print handwriting analysis will also deepen your understanding of what problems can arise when you use neural networks.

That will leave you well prepared to quickly pick up other techniques, as you need them.

The cross-entropy cost function Most of us find it unpleasant to be wrong. Soon after beginning to learn the piano I gave my first performance before an audience.

Write My Paper - Best Professional College Essay Writing Service Introduction[ edit ] Sonnet 1 is the first in a series of sonnets written by William Shakespeare and published in by Thomas Thorpe.

I was nervous, and began playing the piece an octave too low. I got confused, and couldn't continue until someone pointed out my error. I was very embarrassed.

Yet while unpleasant, we also learn quickly when we're decisively wrong. You can bet that the next time I played before an audience I played in the correct octave!

By contrast, we learn more slowly when our errors are less well-defined. Ideally, we hope and expect that our neural networks will learn fast from their errors.

Is this what happens in practice? To answer this question, let's look at a toy example. The example involves a neuron with just one input: We'll train this neuron to do something ridiculously easy: Of course, this is such a trivial task that we could easily figure out an appropriate weight and bias by hand, without using a learning algorithm.

However, it turns out to be illuminating to use gradient descent to attempt to learn a weight and bias. So let's take a look at how the neuron learns.

These are generic choices used as a place to begin learning, I wasn't picking them to be special in any way. Note that this isn't a pre-recorded animation, your browser is actually computing the gradient, then using the gradient to update the weight and bias, and displaying the result.

I'll remind you of the exact form of the cost function shortly, so there's no need to go and dig up the definition. Note that you can run the animation multiple times by clicking on "Run" again.

Click on "Run" again: Indeed, for the first or so learning epochs, the weights and biases don't change much at all. This behaviour is strange when contrasted to human learning. As I said at the beginning of this section, we often learn fastest when we're badly wrong about something. But we've just seen that our artificial neuron has a lot of difficulty learning when it's badly wrong - far more difficulty than when it's just a little wrong.

What's more, it turns out that this behaviour occurs not just in this toy model, but in more general networks. Why is learning so slow? And can we find a way of avoiding this slowdown?

So saying "learning is slow" is really the same as saying that those partial derivatives are small.The Spiders Part I: The Golden Sea The Context of the Film Fritz Lang's The Spiders () is a motion picture serial.

Like the serial work of Louis Feuillade, it is made up of an irregularly long series of films, each around an hour in only made two of the four films he planned in this series: The Golden Sea, and The Diamond Spiders are a mysterious gang, who are up to no.

Humans have a thing for perfection and order, and although most of us are getting worse at it every day, handwriting is no exception.

True, it might be less important these days, but we mustn't dismiss the affect first impressions have on forming someone's opinion of you: if a handwritten note or letter takes the place of a face-to-face introduction, what and how you've written will be judged.
