Overview of this book

Thanks to a number of recent breakthroughs, self-driving car technology is now an emerging subject in the field of artificial intelligence and has shifted data scientists' focus to building autonomous cars that will transform the automotive industry. This book is a comprehensive guide to use deep learning and computer vision techniques to develop autonomous cars. Starting with the basics of self-driving cars (SDCs), this book will take you through the deep neural network techniques required to get up and running with building your autonomous vehicle. Once you are comfortable with the basics, you'll delve into advanced computer vision techniques and learn how to use deep learning methods to perform a variety of computer vision tasks such as finding lane lines, improving image classification, and so on. You will explore the basic structure and working of a semantic segmentation model and get to grips with detecting cars using semantic segmentation. The book also covers advanced applications such as behavior-cloning and vehicle detection using OpenCV, transfer learning, and deep learning methodologies to train SDCs to mimic human driving. By the end of this book, you'll have learned how to implement a variety of neural networks to develop your own autonomous vehicle using modern Python libraries.

The YOLO loss function

The YOLO loss function is calculated in the following steps: 

  1. First, we find the bounding boxes with the highest intersection over union (IoU) and with the correct bounding boxes.
  2. Then, we calculate the confidence loss, which means the probability of the object being present inside a given bounding box.
  3. Next, we calculate the classification loss, which indicates the present class of objects within the bounding box.
  4. Finally, we calculate the coordinate loss for matching the detected boxes.

In summary, the total loss function is as follows:

In the next section, we will learn about the YOLO architecture.
