Training Systems using Python Statistical Modeling

Overview of this book

Python's ease-of-use and multi-purpose nature has made it one of the most popular tools for data scientists and machine learning developers. Its rich libraries are widely used for data analysis, and more importantly, for building state-of-the-art predictive models. This book is designed to guide you through using these libraries to implement effective statistical models for predictive analytics. You’ll start by delving into classical statistical analysis, where you will learn to compute descriptive statistics using pandas. You will focus on supervised learning, which will help you explore the principles of machine learning and train different machine learning models from scratch. Next, you will work with binary prediction models, such as data classification using k-nearest neighbors, decision trees, and random forests. The book will also cover algorithms for regression analysis, such as ridge and lasso regression, and their implementation in Python. In later chapters, you will learn how neural networks can be trained and deployed for more accurate predictions, and understand which Python libraries can be used to implement them. By the end of this book, you will have the knowledge you need to design, build, and deploy enterprise-grade statistical models for machine learning using Python and its rich ecosystem of libraries for predictive analytics.

Summary

In this chapter, we learned all about kNN classifiers and how to train them. We looked at decision trees and how to fit and visualize it. Then, we learned about random forests and how to train them. We looked at Naive Bayes classifiers, and trained one using the Titanic dataset. We then used SVMs on the Titanic dataset and learned how they work. We also looked at logistic regression. Finally, we learned how to find out multiple outcomes for all the classifiers that we worked on in this chapter.

In this next chapter, we will move on to regression, where we want to predict the value of a continuous variable, not a discrete class.
