Hands-On Machine Learning with C++

By: Kirill Kolodiazhnyi

Overview of this book

C++ can make your machine learning models run faster and more efficiently. This handy guide will help you learn the fundamentals of machine learning (ML), showing you how to use C++ libraries to get the most out of your data. This book makes machine learning with C++ for beginners easy with its example-based approach, demonstrating how to implement supervised and unsupervised ML algorithms through real-world examples. This book will get you hands-on with tuning and optimizing a model for different use cases, assisting you with model selection and the measurement of performance. You’ll cover techniques such as product recommendations, ensemble learning, and anomaly detection using modern C++ libraries such as PyTorch C++ API, Caffe2, Shogun, Shark-ML, mlpack, and dlib. Next, you’ll explore neural networks and deep learning using examples such as image classification and sentiment analysis, which will help you solve various problems. Later, you’ll learn how to handle production and deployment challenges on mobile and cloud platforms, before discovering how to export and import models using the ONNX format. By the end of this C++ book, you will have real-world machine learning and C++ knowledge, as well as the skills to use C++ to build powerful ML systems.

Summary

In this chapter, we learned that dimensionality reduction is the process of transferring data that has a higher dimension into a new representation of data with a lower dimension. It is used to reduce the number of correlated features in a dataset and extract the most informative features. Such a transformation can help increase the performance of other algorithms, reduce computational complexity, and make human-readable visualizations.

We learned that there are two different approaches to solve this task. One is feature selection, which doesn't create new features, while the second one is dimensionality reduction algorithms, which make new feature sets. We also learned that dimensionality reduction algorithms are linear and non-linear and that we should select either type, depending on our data. We saw that there are a lot of different algorithms with different properties...
