Deep Learning with PyTorch

Building Blocks of Neural Networks

Understanding the basic building blocks of a neural network, such as tensors, tensor operations, and gradient descents, is important for building complex neural networks. In this chapter, we will build our first Hello world program in neural networks by covering the following topics:

  • Installing PyTorch
  • Implementing our first neural network
  • Splitting the neural network into functional blocks
  • Walking through each fundamental block covering tensors, variables, autograds, gradients, and optimizers
  • Loading data using PyTorch

Installing PyTorch

PyTorch is available as a Python package and you can either use pip, or conda, to build it or you can build it from source. The recommended approach for this book is to use the Anaconda Python 3 distribution. To install Anaconda, please refer to the Anaconda official documentation at https://conda.io/docs/user-guide/install/index.html. All the examples will be available as Jupyter Notebooks in the book's GitHub repository. I would strongly recommend you use Jupyter Notebook, since it allows you to experiment interactively. If you already have Anaconda Python installed, then you can proceed with the following steps for PyTorch installation.

For GPU-based installation with Cuda 8:

conda install pytorch torchvision cuda80 -c soumith

For GPU-based installation with Cuda 7.5:

conda install pytorch torchvision -c soumith

For non-GPU-based installation:

conda...

Our first neural network

We present our first neural network, which learns how to map training examples (input array) to targets (output array). Let's assume that we work for one of the largest online companies, Wondermovies, which serves videos on demand. Our training dataset contains a feature that represents the average hours spent by users watching movies on the platform and we would like to predict how much time each user would spend on the platform in the coming week. It's just an imaginary use case, don't think too much about it. Some of the high-level activities for building such a solution are as follows:

  • Data preparation: The get_data function prepares the tensors (arrays) containing input and output data
  • Creating learnable parameters: The get_weights function provides us with tensors containing random values that we will optimize to solve our problem...

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...

Description

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.

Who is this book for?

This book is for machine learning engineers, data analysts, data scientists interested in deep learning and are looking to explore implementing advanced algorithms in PyTorch. Some knowledge of machine learning is helpful but not a mandatory need. Working knowledge of Python programming is expected.

What you will learn

  • • Use PyTorch for GPU-accelerated tensor computations
  • • Build custom datasets and data loaders for images and test the models using torchvision and torchtext
  • • Build an image classifier by implementing CNN architectures using PyTorch
  • • Build systems that do text classification and language modeling using RNN, LSTM, and GRU
  • • Learn advanced CNN architectures such as ResNet, Inception, Densenet, and learn how to use them for transfer learning
  • • Learn how to mix multiple models for a powerful ensemble model
  • • Generate new images using GAN's and generate artistic images using style transfer

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
