Hands-On Deep Learning with TensorFlow

By: Dan Van Boxel

Overview of this book

Dan Van Boxel’s Deep Learning with TensorFlow is based on Dan’s best-selling TensorFlow video course. With deep learning going mainstream, making sense of data and getting accurate results using deep networks is possible. Dan Van Boxel will be your guide to exploring the possibilities with deep learning; he will enable you to understand data like never before. With the efficiency and simplicity of TensorFlow, you will be able to process your data and gain insights that will change how you look at data. With Dan’s guidance, you will dig deeper into the hidden layers of abstraction using raw data. Dan then shows you various complex algorithms for deep learning and various examples that use these deep neural networks. You will also learn how to train your machine to craft new features to make sense of deeper layers of data. In this book, Dan shares his knowledge across topics such as logistic regression, convolutional neural networks, recurrent neural networks, training deep networks, and high level interfaces. With the help of novel practical examples, you will become an ace at advanced multilayer networks, image recognition, and beyond.

Results of the multiple hidden layer

Now, we'll look into what's going on inside a deep neural network. First, we'll verify the model accuracy. Then, we'll visualize and study the pixel weights. Finally, we'll look at the output weights as well.

After you've trained your deep neural network, let's take a look at the model accuracy. We'll do this the same way that we did for the single hidden layer model. The only difference this time, is that we have many more saved samples of the training and testing accuracy, having gone from many more epochs.

As always, don't worry if you don't have Matplotlib; printing parts of the arrays is fine.

Understanding the multiple hidden layers graph

Execute the following code to see the result:

# Plot the accuracy curves

From the preceding output graph, we reach about 68 percent training accuracy and maybe 63 percent validation accuracy. This isn't too bad, but it does leave room for some...
