Overview of this book

Deep learning powers the most intelligent systems in the world, such as Google Voice, Siri, and Alexa. Advancements in powerful hardware, such as GPUs, software frameworks such as PyTorch, Keras, TensorFlow, and CNTK along with the availability of big data have made it easier to implement solutions to problems in the areas of text, vision, and advanced analytics. This book will get you up and running with one of the most cutting-edge deep learning libraries—PyTorch. PyTorch is grabbing the attention of deep learning researchers and data science professionals due to its accessibility, efficiency and being more native to Python way of development. You'll start off by installing PyTorch, then quickly move on to learn various fundamental blocks that power modern deep learning. You will also learn how to use CNN, RNN, LSTM and other networks to solve real-world problems. This book explains the concepts of various state-of-the-art deep learning architectures, such as ResNet, DenseNet, Inception, and Seq2Seq, without diving deep into the math behind them. You will also learn about GPU computing during the course of the book. You will see how to train a model with PyTorch and dive into complex neural networks such as generative networks for producing text and images. By the end of the book, you'll be able to implement deep learning applications in PyTorch with ease.

Summary

In this chapter, we explored various data structures and operations provided by PyTorch. We implemented several components, using the fundamental blocks of PyTorch. For our data preparation, we created the tensors used by our algorithm. Our network architecture was a model for learning to predict average hours spent by users on our Wondermovies platform. We used the loss function to check the standard of our model and used the optimize function to adjust the learnable parameters of our model to make it perform better.

We also looked at how PyTorch makes it easier to create data pipelines by abstracting away several complexities that would require us to parallelize and augment data.

In the next chapter, we will dive deep into how neural networks and deep learning algorithms work. We will explore various PyTorch built-in modules for building network architectures, loss...
