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.

Improving the Model Performance by Removing Outliers
In the Data visualization section, we saw that some predictors have outliers. Outliers are the values that, when compared to others, are particularly extreme. Outliers are a problem because they tend to distort data analysis results, in particular, in descriptive statistics and correlations. Outliers have a large influence on the fit, because squaring the residuals magnifies the effects of these extreme data points. For these reasons, it may be necessary to remove these values first to improve the performance of the model.
