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.

Convolutional network on sequence data

We learned how CNNs solve problems in computer vision by learning features from the images. In images, CNNs work by convolving across height and width. In the same way, time can be treated as a convolutional feature. One-dimensional convolutions sometimes perform better than RNNs and are computationally cheaper. In the last few years, companies like Facebook have shown success in audio generation and machine translation. In this section, we will learn how CNNs can be used to build a text classification solution.

Understanding one-dimensional convolution for sequence data

In Chapter 5, Deep Learning for Computer Vision, we have seen how two-dimensional weights are learned from the training...
