Overview of this book

Keras 2.x Projects explains how to leverage the power of Keras to build and train state-of-the-art deep learning models through a series of practical projects that look at a range of real-world application areas. To begin with, you will quickly set up a deep learning environment by installing the Keras library. Through each of the projects, you will explore and learn the advanced concepts of deep learning and will learn how to compute and run your deep learning models using the advanced offerings of Keras. You will train fully-connected multilayer networks, convolutional neural networks, recurrent neural networks, autoencoders and generative adversarial networks using real-world training datasets. The projects you will undertake are all based on real-world scenarios of all complexity levels, covering topics such as language recognition, stock volatility, energy consumption prediction, faster object classification for self-driving vehicles, and more. By the end of this book, you will be well versed with deep learning and its implementation with Keras. You will have all the knowledge you need to train your own deep learning models to solve different kinds of problems.

Summary

In this chapter, we have learned about the basics of CNNs. To begin with, the basic concepts of computer vision were analyzed. Computer vision is the discipline that studies how to enable computers to understand and interpret visual information that's present in images or videos. This also deals with the analysis of numerical images.

Then, the architecture of convolutional network models was explored. A CNN consists of a series of layers such as input, convolutional, ReLU, pool, and fully connected layers. Each identify as a level of the CNN. The convolutional layer is the main level of the network. Its goal is to identify patterns, such as curves, angles, circumferences, or squares that have been depicted in an image with high accuracy. The ReLU layer aims to erase negative values that have been obtained in previous levels, and it is usually placed after convolutional...
