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.

ML model serialization APIs in C++ libraries

In this section, we will discuss the ML model sharing APIs in the Dlib, Shogun, Shark-ML, and PyTorch libraries. There are three main types of sharing ML models among the different C++ libraries:

  • Share model parameters (weights)
  • Share the entire model's architecture
  • Share both the model architecture and its trained parameters

In the following sections, we will look at what API is available in each library and emphasize what type of sharing it supports.

Model serialization with Dlib

The Dlib library uses the serialization API for decision_function and neural network type objects. Let's learn how to use it by implementing a real example.

First, we define the types for...
