Data normalization is a crucial preprocessing step in machine learning. In general, data normalization is a process that transforms multiscaled data to the same scale. Feature values in a dataset can have very different scales—for example, the height can be given in centimeters with small values, but the income can have large-value amounts. This fact has a significant impact on many machine learning algorithms. For example, if some feature values differ from values of other features several times, then this feature will dominate over others in classification algorithms based on the Euclidean distance. Some algorithms have a strong requirement for normalization of input data; an example of such an algorithm is the Support Vector Machine (SVM) algorithm. Neural networks also usually require normalized input data. Also, data normalization has an impact on...

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.
