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.

Generating music using deep learning

In the previous chapter, we learned about generating text by going through a novel. In this section, we will learn about generating audio from a sequence of audio notes.

Getting ready

A MIDI file typically contains information about the notes and chords of the audio file, whereas the note object contains information about the pitch, octave, and offset of the notes. The chord object contains a set of notes that are played at the same time.

The strategy that we'll adopt to build a music generator is as follows:

  • Extract the notes present in audio file
  • Assign a unique ID for each note.
  • Take a sequence of 100 historical notes, and the 101st note shall be the output.
  • Fit an LSTM model...
