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.

Stock price prediction

In the previous sections, we learned about performing audio, text, and structured data analysis using neural networks. In this section, we will learn about performing a time-series analysis using a case study of predicting a stock price.

Getting ready

To predict a stock price, we will perform the following steps:

  1. Order the dataset from the oldest to the newest date.
  2. Take the first five stock prices as input and the sixth stock price as output.
  3. Slide it across so that in the next data point the second to the sixth data points are input and the seventh data point is the output, and so on, till we reach the final data point.
  4. Given that it is a continuous number that we are predicting, the loss function...
