Overview of this book

The independent recipes in Machine Learning Using TensorFlow Cookbook will teach you how to perform complex data computations and gain valuable insights into your data. Dive into recipes on training models, model evaluation, sentiment analysis, regression analysis, artificial neural networks, and deep learning - each using Google’s machine learning library, TensorFlow. This cookbook covers the fundamentals of the TensorFlow library, including variables, matrices, and various data sources. You’ll discover real-world implementations of Keras and TensorFlow and learn how to use estimators to train linear models and boosted trees, both for classification and regression. Explore the practical applications of a variety of deep learning architectures, such as recurrent neural networks and Transformers, and see how they can be used to solve computer vision and natural language processing (NLP) problems. With the help of this book, you will be proficient in using TensorFlow, understand deep learning from the basics, and be able to implement machine learning algorithms in real-world scenarios.

Implementing Lasso and Ridge regression

There are ways to limit the influence of coefficients on the regression output. These methods are called regularization methods, and two of the most common regularization methods are Lasso and Ridge regression. We cover how to implement both of these in this recipe.

Getting ready

Lasso and Ridge regression are very similar to regular linear regression, except that we add regularization terms to limit the slopes (or partial slopes) in the formula. There may be multiple reasons for this, but a common one is that we wish to restrict the number of features that have an impact on the dependent variable.

How to do it...

We proceed with the recipe as follows:

We will use the Boston Housing dataset again and set up our functions in the same way as in the previous recipes. In particular we need define_feature_columns_layers, make_input_fn, and create_interactions. We again first load the libraries, and then we define a new create_ridge_linreg...
