Overview of this book

This book, written by an HPC expert with over 25 years of experience, guides you through enhancing model training performance using PyTorch. Here you’ll learn how model complexity impacts training time and discover performance tuning levels to expedite the process, as well as utilize PyTorch features, specialized libraries, and efficient data pipelines to optimize training on CPUs and accelerators. You’ll also reduce model complexity, adopt mixed precision, and harness the power of multicore systems and multi-GPU environments for distributed training. By the end, you'll be equipped with techniques and strategies to speed up training and focus on building stunning models.

Knowing the model simplifying process

In simpler words, simplifying a model concerns removing connections, neurons, or entire layers of the neural network to get a lighter model, i.e., a model with a reduced number of parameters. Naturally, the efficiency of the simplified version must be very close to the one achieved by the original model. Otherwise, simplifying the model does not make any sense.

To understand this topic, we must answer the following questions:

  • Why simplify a model? (reason)
  • How do we simplify a model? (process)
  • When do we simplify a model? (moment)

We will go through each of these questions in the following sections to get an overall understanding of model simplification.

Note

Before moving on in this chapter, it is essential to say that model simplification is still an open research area. Consequently, some concepts and terms cited in this book may differ a little bit from other materials or how they are employed on frameworks and...
