scikit-learn Cookbook

By: John Sukup

Overview of this book

Trusted by data scientists, ML engineers, and software developers alike, scikit-learn offers a versatile, user-friendly framework for implementing a wide range of ML algorithms, enabling the efficient development and deployment of predictive models in real-world applications. This third edition of scikit-learn Cookbook will help you master ML with real-world examples and scikit-learn 1.5 features. This updated edition takes you on a journey from understanding the fundamentals of ML and data preprocessing, through implementing advanced algorithms and techniques, to deploying and optimizing ML models in production. Along the way, you’ll explore practical, step-by-step recipes that cover everything from feature engineering and model selection to hyperparameter tuning and model evaluation, all using scikit-learn. By the end of this book, you’ll have gained the knowledge and skills needed to confidently build, evaluate, and deploy sophisticated ML models using scikit-learn, ready to tackle a wide range of data-driven challenges. *Email sign-up and proof of purchase required

ElasticNet and Regularization

ElasticNet is a hybrid of Ridge and Lasso regression which combines their strengths to handle different types of data. With ElasticNet, we can control the strength of the regularization using the alpha parameter, which is similar to the alpha parameter in Ridge and Lasso regression. We can also control the mix of Ridge and Lasso regularization using the l1_ratio parameter, which controls the proportion of Ridge and Lasso regularization in the model. This is useful when we have a dataset with a mix of features that are highly correlated with each other and some that are not. This recipe will introduce you to a technique that blends the benefits of both regularization techniques we covered previously.

Getting ready

In order to implement ElasticNet regression, we'll use the ElasticNet() class from the sklearn.linear_model module. This class is similar to Ridge and Lasso regression, but it combines their strengths to handle different types of data. We can...
