Keras 2.x Projects

By: Giuseppe Ciaburro

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.

Genetic programming and evolutionary strategies

In artificial intelligence, genetic algorithms are part of the class of evolutionary algorithms. The characteristic of the latter is the finding of solutions to problems using techniques borrowed from natural evolution. The search for a solution to a problem is entrusted to an iterative process that selects and recombines more and more refined solutions until a criterion of optimality is reached. In a genetic algorithm, the population of solutions is pushed toward a given objective by the evolutionary pressure.

In the following diagram is shown a flowchart of a genetic algorithm:

Evolutionary algorithm is obtained through a particular function, called the fitness function, which is able to synthesize the quality of the solution in a single parameter. Each solution consists of a set of genes. These genes take part in the recombination...
