Hands-On Python Deep Learning for the Web

By: Anubhav Singh, Sayak Paul

Overview of this book

When used effectively, deep learning techniques can help you develop intelligent web apps. In this book, you'll cover the latest tools and technological practices that are being used to implement deep learning in web development using Python. Starting with the fundamentals of machine learning, you'll focus on DL and the basics of neural networks, including common variants such as convolutional neural networks (CNNs). You'll learn how to integrate them into websites with the frontends of different standard web tech stacks. The book then helps you gain practical experience of developing a deep learning-enabled web app using Python libraries such as Django and Flask by creating RESTful APIs for custom models. Later, you'll explore how to set up a cloud environment for deep learning-based web deployments on Google Cloud and Amazon Web Services (AWS). Next, you'll learn how to use Microsoft's intelligent Emotion API, which can detect a person's emotions through a picture of their face. You'll also get to grips with deploying real-world websites, in addition to learning how to secure websites using reCAPTCHA and Cloudflare. Finally, you'll use NLP to integrate a voice UX through Dialogflow on your web pages. By the end of this book, you'll have learned how to deploy intelligent web apps and websites with the help of effective tools and practices.

An introduction to CNTK

CNTK is an offering by Microsoft. The framework is a part of the ONNX format initiative, which allows easy conversion of models between different neural toolkit frameworks. The framework is responsible for a huge portion of the deep learning production workload on Microsoft software and platforms. Launched in 2016, the framework has been a contender to popular frameworks such as TensorFlow, PyTorch, and so on. The framework is completely open source and can be found at https://github.com/microsoft/CNTK.

CNTK powers enterprise services, such as Cortana and Bing, and advertisements, such as Skype Translate, Microsoft Cognitive Services, and several others. It has been proven to work faster than competitors such as TensorFlow and PyTorch on several applications.

In this section, we will study some fundamentals of CNTK and then proceed to create a Django application...
