Overview of this book

With the surge in artificial intelligence in applications catering to both business and consumer needs, deep learning is more important than ever for meeting current and future market demands. With this book, you’ll explore deep learning, and learn how to put machine learning to use in your projects. This second edition of Python Deep Learning will get you up to speed with deep learning, deep neural networks, and how to train them with high-performance algorithms and popular Python frameworks. You’ll uncover different neural network architectures, such as convolutional networks, recurrent neural networks, long short-term memory (LSTM) networks, and capsule networks. You’ll also learn how to solve problems in the fields of computer vision, natural language processing (NLP), and speech recognition. You'll study generative model approaches such as variational autoencoders and Generative Adversarial Networks (GANs) to generate images. As you delve into newly evolved areas of reinforcement learning, you’ll gain an understanding of state-of-the-art algorithms that are the main components behind popular games Go, Atari, and Dota. By the end of the book, you will be well-versed with the theory of deep learning along with its real-world applications.

Intuition and justification of generative models

So far, we've used neural networks as discriminative models. This simply means that given input data, a discriminative model will map it to a certain label (in other words, a classification). A typical example is the classification of MNIST images in 1 of 10 digit classes, where the neural network maps the input data features (pixel intensities) to the digit label. We can also say this in another way, a discriminative model gives us the probability of (class), given (input) . In the MNIST case, this is the probability of the digit, given the pixel intensities of the image.

On the other hand, a generative model learns the distribution of the classes. You can think of it as the opposite of what the discriminative model does. Instead of predicting the class probability, , given certain input features, it tries to predict the...
