Overview of this book

This book will take you from the basics of neural networks to advanced implementations of architectures using a recipe-based approach. We will learn about how neural networks work and the impact of various hyper parameters on a network's accuracy along with leveraging neural networks for structured and unstructured data. Later, we will learn how to classify and detect objects in images. We will also learn to use transfer learning for multiple applications, including a self-driving car using Convolutional Neural Networks. We will generate images while leveraging GANs and also by performing image encoding. Additionally, we will perform text analysis using word vector based techniques. Later, we will use Recurrent Neural Networks and LSTM to implement chatbot and Machine Translation systems. Finally, you will learn about transcribing images, audio, and generating captions and also use Deep Q-learning to build an agent that plays Space Invaders game. By the end of this book, you will have developed the skills to choose and customize multiple neural network architectures for various deep learning problems you might encounter.

Detecting a person using an anchor box-based algorithm

One of the drawbacks of region proposal based CNN is that it does not enable a real-time object recognition, as selective search takes considerable time to propose regions. This results in region proposal-based object detection algorithms not being useful in cases like self-driving car, where real-time detection is very important.

In order to achieve real-time detection, we will build a model that is inspired by the You Only Look Once (YOLO) algorithm from scratch that looks at the images that contain a person in image and draws a bounding box around the person in image.

Getting ready

To understand how YOLO overcomes the drawback of consuming considerable time in generating...
