Practical Projects with Keras 2.X

By: Barbora stetinova

Overview of this book

Keras is a user-friendly, modular, and intuitive neural network library that enables you to experiment with deep neural networks. Practical Projects with Keras 2.x 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. You'll begin by exploring concepts underlying regression, such as the differences between simple and multiple regression and algebraically representing a multiple linear regression problem. Moving on, you'll discover various classification techniques, such as Naive Bayes and Mixture Gaussian, and use these to solve practical problems. The course ends by teaching you the basic concepts of multilayer neural networks and how to implement them in Keras environment. By the end of this course, you will have the knowledge you need to train your own deep learning models to solve different kinds of problems.

Basics of Classification Problems
Classifiers identify the class of a new objective, based on knowledge that's been extracted from a series of samples (dataset). Starting from a dataset, a classifier extracts a model, which is then used to classify the new instances. Examples of classifiers are as follows: - The texts classifier - The image classifier - The medical classifier The classifier is a system with some characteristics that allow you to identify the class of the sample examined. In different classification methods, groups are called classes. The goal of a classifier is to establish the classification criterion to maximize performance. The performance of a classifier is measured by evaluating the capacity for generalization. Generalization means attributing the correct class to each new experimental observation. The way in which these classes are identified discriminates between the different methods that are available.
