Overview of this book

<p><span id="description" class="sugar_field">Neural Networks are used all around us: they index photos into categories, translate text, suggest replies for emails, and beat the best games. Many people are eager to apply this knowledge to their own data, but many fail to achieve the results they expect.</span></p> <p><span id="description" class="sugar_field">In this course, we’ll start by building a simple flower recognition program, making you feel comfortable with Tensorflow, and it will teach you several important concepts in Neural Networks. Next, you’ll start working with high-dimensional uses to predict one output: 1275 molecular features you can use to predict the atomization energy of an atom. The next program we’ll create is a handwritten number recognition system trained on the famous MNIST dataset. We’ll work our way up from a simple multilayer perceptron to a state of the art Deep Convolutional Neural Network. </span></p> <p><span id="description" class="sugar_field">In the final program, estimate what a celebrity looks like, checking for new pictures to see whether a celebrity is attractive, wears a hat, has lipstick on, and many more properties that are difficult to estimate with "traditional" computer vision techniques.</span></p> <p><span id="description" class="sugar_field">After the course, you’ll not only be able to build a Neural Network for your own dataset, you’ll also be able to reason which techniques will improve your Neural Network.</span></p> <h2><span class="sugar_field">Style and Approach</span></h2> <p><span class="sugar_field"><span id="trade_selling_points_c" class="sugar_field">The video is packed with step-by-step instructions, working examples, and helpful advice about building your Neural Network with Tensorflow. You'll learn to build your own network. This practical course is divided into clear byte-size chunks so you can learn at your own pace and focus on the areas of most interest to you.&nbsp;</span></span></p>

Section 5
The Importance of Hyperparameters
There are several better methods to estimate these hyperparameters, and we will try grid-search over the learning rate parameter to improve our performance. - Learn what hyperparameters are - Learn about methods to tweak hyperparameters - Do a grid-search over the learning rate variable
