One day you're working away in your office, designing logical circuits, setting out AND gates, OR gates, and so on, when your boss walks in with bad news.
The customer has just added a surprising design requirement: You're dumbfounded, and tell your boss: But what the customer wants, they get. Suppose you're allowed to use a special logical gate which lets you AND together as many inputs as you want. With these special gates it turns out to be possible to compute any function at all using a circuit that's just two layers deep.
But just because something is possible doesn't make it a good idea. In practice, when solving circuit design problems or most any kind of algorithmic problemwe usually start by figuring out how to solve sub-problems, and handwriting analysis number 0 gradually integrate the solutions.
In other words, we build up to a solution through multiple layers of abstraction. For instance, suppose we're designing a logical circuit to multiply two numbers. Chances are we want to build it up out of sub-circuits doing operations like adding two numbers.
The sub-circuits for adding two numbers will, in turn, be built up out of sub-sub-circuits for adding two bits. Very roughly speaking our circuit will look like: That is, our final circuit contains at least three layers of circuit elements. In fact, it'll probably contain more than three layers, as we break the sub-tasks down into smaller units than I've described.
But you get the general idea. So deep circuits make the process of design easier. But they're not just helpful for design. There are, in fact, mathematical proofs showing that for some functions very shallow circuits require exponentially more circuit elements to compute than do deep circuits.
On the other hand, if you use deeper circuits it's easy to compute the parity using a small circuit: Deep circuits thus can be intrinsically much more powerful than shallow circuits.
Up to now, this book has approached neural networks like the crazy customer.
Almost all the networks we've worked with have just a single hidden layer of neurons plus the input and output layers: These simple networks have been remarkably useful: Nonetheless, intuitively we'd expect networks with many more hidden layers to be more powerful: Such networks could use the intermediate layers to build up multiple layers of abstraction, just as we do in Boolean circuits.
For instance, if we're doing visual pattern recognition, then the neurons in the first layer might learn to recognize edges, the neurons in the second layer could learn to recognize more complex shapes, say triangle or rectangles, built up from edges.
The third layer would then recognize still more complex shapes. These multiple layers of abstraction seem likely to give deep networks a compelling advantage in learning to solve complex pattern recognition problems.

In this chapter, we'll try training deep networks using our workhorse learning algorithm - stochastic gradient descent by backpropagation.
But we'll run into trouble, with our deep networks not performing much if at all better than shallow networks. That failure seems surprising in the light of the discussion above. Rather than give up on deep networks, we'll dig down and try to understand what's making our deep networks hard to train.
When we look closely, we'll discover that the different layers in our deep network are learning at vastly different speeds. In particular, when later layers in the network are learning well, early layers often get stuck during training, learning almost nothing at all.
This stuckness isn't simply due to bad luck. Rather, we'll discover there are fundamental reasons the learning slowdown occurs, connected to our use of gradient-based learning techniques.
As we delve into the problem more deeply, we'll learn that the opposite phenomenon can also occur: In fact, we'll find that there's an intrinsic instability associated to learning by gradient descent in deep, many-layer neural networks.As a member, you'll also get unlimited access to over 75, lessons in math, English, science, history, and more.

The goal of capital letters is granting value to a proper name, highlighting a word or phrase to catch the reader´s attention.
Capitals letters are used at the beginning of a line or paragraph. What Does Your Handwriting Say About You?
graphology Graphology is the study of handwriting, especially when employed as a means of analyzing a writer's character, personality, abilities, etc. Handwriting pages for writing numbers For preschoolers just starting to write their numbers, I recommend my Numbers of All Sizes handwriting pages.
Your child starts on at the red dot and follows the arrow to write inside each block letter. While browsing in a book store, Andrea McNichol’s book “Handwriting Analysis-Putting It to Work for You” caught my eye, and I bought it, curious about what one could tell from someone’s handwriting.
Handwriting analysis (also known as graphology) can even be used for detecting lies and revealing possible health ailments. Check out the infographic below to learn what your handwriting .
