Backpropagation in PyTorch

This lesson introduces you to PyTorch and focuses on two main concepts: PyTorch tensors and the autograd module. We are going to get our hands dirty throughout the lesson, using a demo environment to explore the methodologies covered. We’ll look at the pros and cons of each method, and when they should be used.

Learning Objectives

• Create a tensor in PyTorch
• Understand when to use the autograd attribute
• Create a dataset in PyTorch
• Understand what backpropagation is and why it is important

Intended Audience

This lesson is intended for anyone interested in machine learning, and especially for data scientists and data engineers.

Prerequisites

To follow along with this lesson, you should have PyTorch version 1.5 or later.
