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 Concepts of Artificial Neural Networks (ANN’s)
ANNs are mathematical models that are able to simulate the usual activities of the human brain such as image perception, pattern recognition, language comprehension, and sensory motor coordination. These models are composed of a system of nodes, equivalent to the neurons of a human brain, which are interconnected by weighted connections, equivalent to the synapses between the neurons. The output of the network is iteratively changed from the link weights up to the convergence. The data to be analyzed is provided via the input level and the result provided by the network is returned from the output level. Input nodes represent the independent or predictive variables used to predict dependent variables, such as output neurons. Here we will learn about: - Basic concepts of ANN’s - Architecture of ANN’s - Paradigms - Supervised Learning - Unsupervised Learning - Semi-Supervised Learning - Understanding the structure of Neural networks - Weights and Biases - Types of activation functions - Unit step activation function - Sigmoid - Hyperbolic Tangent - Rectified Linear Unit (ReLU)
