Overview of this book

Deep Learning is revolutionizing a wide range of industries. For many applications, deep learning has proven to outperform humans by making faster and more accurate predictions. This book provides a top-down and bottom-up approach to demonstrate deep learning solutions to real-world problems in different areas. These applications include Computer Vision, Natural Language Processing, Time Series, and Robotics. The Python Deep Learning Cookbook presents technical solutions to the issues presented, along with a detailed explanation of the solutions. Furthermore, a discussion on corresponding pros and cons of implementing the proposed solution using one of the popular frameworks like TensorFlow, PyTorch, Keras and CNTK is provided. The book includes recipes that are related to the basic concepts of neural networks. All techniques s, as well as classical networks topologies. The main purpose of this book is to provide Python programmers a detailed list of recipes to apply deep learning to common and not-so-common scenarios.

Introduction

In this chapter, we will focus on data that is less static but streaming. Specifically, it is data where the temporal element plays a crucial role in the distribution of the data, such as speech and video. When processing such data, the distribution of the input data can often change rapidly over time. For example, in sensor data, we can have small peaks during rush hour and there can be a lot of changes in a video of a sports game. Another challenge with types of data is the size of the dataset for training. The datasets used for video classification are often larger than 100 GB. This means computing power is essential.
