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.

Low-dimensional representation

We have now reached the final section of this book, and in this section, we will be talking about low-dimensional representation. We will see what multidimensional scaling (MDS) is, and demonstrate how to perform it.

With MDS, we start with a distance matrix. This could have been computed in any way, using any distance metric we want. Having gotten the distance matrix, we then construct Euclidean coordinates for each point. Perhaps these coordinates representing our data preserve the distances described in the original matrix. If it is not possible, however, we can only hope that the error between the actual and constructed distances is small.

Example of MDS

MDS creates points that are some specified...
