Hands-On Machine Learning with C++

Introduction to Machine Learning with C++

There are different approaches to making computers solve tasks. One of them is to define an explicit algorithm, and another one is to use implicit strategies based on mathematical and statistical methods. Machine learning (ML) is one of the implicit methods that uses mathematical and statistical approaches to solve tasks. It is an actively growing discipline, and a lot of scientists and researchers find it to be one of the best ways to move forward toward systems acting as human-level artificial intelligence (AI).

In general, ML approaches have the idea of searching patterns in a given dataset as their basis. Consider a recommendation system for a news feed, which provides the user with a personalized feed based on their previous activity or preferences. The software gathers information about the type of news article the user reads and calculates some statistics. For example, it could be the frequency of some topics appearing in a set of...

Understanding the fundamentals of ML

There are different approaches to creating and training ML models. In this section, we show what these approaches are and how they differ. Apart from the approach we use to create an ML model, there are also parameters that manage how this model behaves in the training and evaluation processes. Model parameters can be divided into two distinct groups, which should be configured in different ways. The first group of parameters is the model weights in ML algorithms that are used to adjust the model’s predictions. They are assigned numerical values during the training process, and these values determine how the model makes decisions or predictions based on new data. The second group is the model hyperparameters that control the behavior of an ML model during training. They are not learned from the data like other parameters in the model but, rather, are set by the user or algorithm before training begins. The last crucial part of the ML process...

An overview of linear algebra

The concepts of linear algebra are essential for understanding the theory behind ML because they help us understand how ML algorithms work under the hood. Also, most ML algorithm definitions use linear algebra terms.

Linear algebra is not only a handy mathematical instrument but also the concepts of linear algebra can be very efficiently implemented with modern computer architectures. The rise of ML, and especially deep learning, began after significant performance improvement of the modern graphics processing unit (GPU). GPUs were initially designed to work with linear algebra concepts and massively parallel computations used in computer games. After that, special libraries were created to work with general linear algebra concepts. Examples of libraries that implement basic linear algebra routines are Cuda and OpenCL, and one example of a specialized linear algebra library is cuBLAS. Moreover, it became more common to use general-purpose graphics processing...

An overview of linear regression

Consider an example of the real-world supervised ML algorithm called linear regression. In general, linear regression is an approach for modeling a target value (dependent value) based on an explanatory value (independent value). This method is used for forecasting and finding relationships between values. We can classify regression methods by the number of inputs (independent variables) and the type of relationship between the inputs and outputs (dependent variables).

Simple linear regression is the case where the number of independent variables is 1, and there is a linear relationship between the independent (x) and dependent (y) variables.

Linear regression is widely used in different areas such as scientific research, where it can describe relationships between variables, as well as in applications within industry, such as revenue prediction. For example, it can estimate a trend line that represents the long-term movement in the stock price...

Summary

In this chapter, we learned what ML is, how it differs from other computer algorithms, and how it became so popular. We also became familiar with the necessary mathematical background required to begin working with ML algorithms. We looked at software libraries that provide APIs for linear algebra and also implemented our first ML algorithm—linear regression.

There are other linear algebra libraries for C++. Moreover, the popular deep learning frameworks use their own implementations of linear algebra libraries. For example, the MXNet framework is based on the mshadow library, and the PyTorch framework is based on the ATen library. Some of these libraries can use GPU or special CPU instructions to speed up calculations. Such features do not usually change the API but require some additional library initialization settings or explicit object conversion to different backends such as CPUs or GPUs.

Real ML projects can be challenging and complex. Common pitfalls include...

The chapters cover techniques such as product recommendations, ensemble learning, anomaly detection, sentiment analysis, and object recognition using modern C++ libraries. You’ll also learn how to overcome production and deployment challenges on mobile platforms, and see how the ONNX model format can help you accomplish these tasks. This new edition has been updated with key topics such as sentiment analysis implementation using transfer learning and transformer-based models, as well as tracking and visualizing ML experiments with MLflow. An additional section shows you how to use Optuna for hyperparameter selection. The section on model deployment into mobile platform now includes a detailed explanation of real-time object detection for Android with C++. By the end of this C++ book, you’ll have real-world machine learning and C++ knowledge, as well as the skills to use C++ to build powerful ML systems.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
