Hands-On Convolutional Neural Networks with TensorFlow

Deep Learning and Convolutional Neural Networks

efore we begin this chapter, we need to talk a bit about AI and machine learning (ML) and how those two components fit together. The term "artificial" refers to something that is not real or natural, whereas "intelligence" refers to something capable of understanding, learning, or able to solve problems (and, in extreme cases, being self-aware).

Officially, artificial intelligence research began at the Dartmouth Conference of 1956 where AI and its mission were defined. In the following years, everyone was optimistic as machines were able to solve algebra problems and learn English, and the first robot was constructed in 1972. However in the 1970s, due to overpromising but under delivering, there was a so-called AI winter where AI research was limited and underfunded. After this though AI was reborn through expert...

AI and ML

For the purpose of this book, consider artificial intelligence (AI) as the field of computer science responsible for making agents (software/robots) that act to solve a specific problem. In this case, "intelligent" means that the agent is flexible and it perceives its environment through sensors and will take actions that maximize its chances to succeed at some particular goal.

We want an AI to maximize something that is named Expected Utility or the probability of getting some sort of satisfaction by doing an action. An easy to understand example of this is by going to school, you will maximize your expected utility of getting a job.

AI aspires to replace the error-prone human intelligence involved in completing tedious everyday tasks. Some central components of human intelligence that AI aims to mimic (and an intelligent agent should have) are:

  • Natural Language...

Artificial neural networks

Very vaguely inspired by the biological network of neurons residing in our brain, artificial neural networks (ANNs) are made up of a collection of units named artificial neurons that are organized into the following three types of layers:

  • Input layer
  • Hidden layer
  • Output layer

The basic artificial neuron works (see the following image) by calculating a dot product between an input and its internal weights, and the results is then passed to a nonlinear activation function f (sigmoid, in this example). These artificial neurons are then connected together to form a network. During the training of this network, the aim is to find the proper set of weights that will help with whatever task we want our network to do:

Next, we have an example of a 2-layer feed forward artificial neural network. Imagine that the connections between neurons are the weights...

Convolutional neural networks

We will now look at another type of neural network that is especially designed to work with data that has some spatial properties, such as images. This type of neural network is called a Convolutional Neural Network (CNN).

A CNN is mainly composed of layers called convolution layers that filter their layer inputs to find useful features within those inputs. This filtering operation is called convolution, which gives rise to the name of this kind of neural network.

The following diagram shows the 2-D convolution operation on an image and its result. It is important to remember that the filter kernel has a depth that matches the depth of the input (3 in this case):

It is also important to be clear that an input to a convolution layer doesn't have to be a 1 or 3 channel image. Input tensors to a convolution layer can have any amount of channels...

Building a CNN model in TensorFlow

Before we start, there is a bit of good news: using TensorFlow, you don't need to take care about writing backpropagation or gradient descent code and also all common types of layers are already implemented, so things should be easier.

In the TensorFlow example here, we will change things a bit from what you learned in Chapter 1, Setup and Introduction to TensorFlow, and use the tf.layers API to create whole layers of our network with ease:

import tensorflow as tf 
from tensorflow.examples.tutorials.mnist import input_data 
mnist = input_data.read_data_sets("MNIST_data/", one_hot=True) 
# MNIST data input (img shape: 28*28) 
num_input = 28*28*1 
# MNIST total classes (0-9 digits) 
num_classes = 10 
 
# Define model I/O (Placeholders are used to send/get information from graph) 
x_ = tf.placeholder("float", shape=[None...

Summary

In this chapter, we introduced you to ML and artificial intelligence. We looked at what artificial neural networks are and how to train them. After this, we looked at CNNs and their main building blocks. We explained how to use TensorFlow to train your own CNN for recognizing digits. Finally, we had an introduction to Tensorboard and saw how it can be used to help visualize important statistics while training models in TensorFlow.

In the next chapter, we are going to look more closely at the task of image classification and how we can use CNNs and TensorFlow to solve this task.

Key benefits

  • Learn the fundamentals of Convolutional Neural Networks
  • Harness Python and Tensorflow to train CNNs
  • Build scalable deep learning models that can process millions of items

Description

Convolutional Neural Networks (CNN) are one of the most popular architectures used in computer vision apps. This book is an introduction to CNNs through solving real-world problems in deep learning while teaching you their implementation in popular Python library - TensorFlow. By the end of the book, you will be training CNNs in no time! We start with an overview of popular machine learning and deep learning models, and then get you set up with a TensorFlow development environment. This environment is the basis for implementing and training deep learning models in later chapters. Then, you will use Convolutional Neural Networks to work on problems such as image classification, object detection, and semantic segmentation. After that, you will use transfer learning to see how these models can solve other deep learning problems. You will also get a taste of implementing generative models such as autoencoders and generative adversarial networks. Later on, you will see useful tips on machine learning best practices and troubleshooting. Finally, you will learn how to apply your models on large datasets of millions of images.

Who is this book for?

This book is for Software Engineers, Data Scientists, or Machine Learning practitioners who want to use CNNs for solving real-world problems. Knowledge of basic machine learning concepts, linear algebra and Python will help.

What you will learn

  • Train machine learning models with TensorFlow
  • Create systems that can evolve and scale during their life cycle
  • Use CNNs in image recognition and classification
  • Use TensorFlow for building deep learning models

This book, although at times has some useful information, has numerous formatting issues that make pages hard to read. its as if no one ready through it completely prior to printing. Also, the chapters feel more like the rough draft, and often lack enough detail to make sense of the subject matter. The authors seemed to have rushed this to print before prematurely

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.
