Neural Network Programming with TensorFlow

Deep Feedforward Networks

In the first chapter, you learned about the mathematics which drives the logic behind all kinds of neural networks. In this chapter, we are going to focus on the most fundamental neutral networks, which are called feedforward neural networks. We will also look at deep feedforward networks with multiple hidden layers to improve the accuracy of the model.

We will be covering the following topics:

  • Defining feedforward networks
  • Understanding backpropagation
  • Implementing feedforward networks in TensorFlow
  • Analyzing the Iris dataset
  • Creating feedforward networks for image classification

Defining feedforward networks

Deep feedforward networks, also called feedforward neural networks, are sometimes also referred to as Multilayer Perceptrons (MLPs). The goal of a feedforward network is to approximate the function of f∗. For example, for a classifier, y=f∗(x) maps an input x to a label y. A feedforward network defines a mapping from input to label y=f(x;θ). It learns the value of the parameter θ that results in the best function approximation.

We discuss RNNs in Chapter 5Recurrent Neural Networks. Feedforward networks are a conceptual stepping stone on the path to recurrent networks, which power many natural language applications. Feedforward neural networks are called networks because they compose together many different functions which represent them. These functions are composed in a directed acyclic graph.

The model...

Understanding backpropagation

When a feedforward neural network is used to accept an input x and produce an output , information flows forward through the network elements. The input x provides the information that then propagates up to the hidden units at each layer and produces . This is called forward propagation. During training, forward propagation continues onward until it produces a scalar cost J(θ). The backpropagation algorithm, often called backprop, allows the information from the cost to then flow backward through the network in order to compute the gradient.

Computing an analytical expression for the gradient is straightforward, but numerically evaluating such an expression can be computationally expensive. The backpropagation algorithm does so using a simple and inexpensive procedure.

Backpropagation refers only to the method to compute the...

Implementing feedforward networks with TensorFlow

Feedforward networks can be easily implemented using TensorFlow by defining placeholders for hidden layers, computing the activation values, and using them to calculate predictions. Let's take an example of classification with a feedforward network:

X = tf.placeholder("float", shape=[None, x_size])
y = tf.placeholder("float", shape=[None, y_size])
weights_1 = initialize_weights((x_size, hidden_size), stddev)
weights_2 = initialize_weights((hidden_size, y_size), stddev)
sigmoid = tf.nn.sigmoid(tf.matmul(X, weights_1))
y = tf.matmul(sigmoid, weights_2)

Once the predicted value tensor has been defined, we calculate the cost function:

cost = tf.reduce_mean(tf.nn.OPERATION_NAME(labels=<actual value>, logits=<predicted value>))
updates_sgd = tf.train.GradientDescentOptimizer(sgd_step).minimize(cost)

Here...

Analyzing the Iris dataset

Let's look at a feedforward example using the Iris dataset.

In the Iris dataset, we will use 150 rows of data made up of 50 samples from each of three Iris species: Iris setosa, Iris virginica, and Iris versicolor.

Petal geometry compared from three iris species:
Iris Setosa, Iris Virginica, and Iris Versicolor.

In the dataset, each row contains data for each flower sample: sepal length, sepal width, petal length, petal width, and flower species. Flower species are stored as integers, with 0 denoting Iris setosa, 1 denoting Iris versicolor, and 2 denoting Iris virginica.

First, we will create a run() function that...

Implementing feedforward networks with images

Now we will look at how to use feedforward networks to classify images. We will be using notMNIST data. The dataset consists of images for nine letters, A to I.

NotMNIST dataset is similar to MNIST dataset but focuses on Alphabets instead of numbers (http://yaroslavvb.blogspot.in/2011/09/notmnist-dataset.html)

We have reduced the original dataset to a smaller version for the training so that you can easily get started. Download the ZIP files and extract them to the folder where the dataset is contained, https://1drv.ms/f/s!Av6fk5nQi2j-kniw-8GtP8sdWejs.

The pickle module of python implements an algorithm for serializing and de-serializing a Python object structure. Pickling is the process in which a Python object hierarchy is converted into a byte stream, unpickling is the inverse operation, where a byte stream is converted back into...

Description

If you're aware of the buzz surrounding the terms such as "machine learning," "artificial intelligence," or "deep learning," you might know what neural networks are. Ever wondered how they help in solving complex computational problem efficiently, or how to train efficient neural networks? This book will teach you just that. You will start by getting a quick overview of the popular TensorFlow library and how it is used to train different neural networks. You will get a thorough understanding of the fundamentals and basic math for neural networks and why TensorFlow is a popular choice Then, you will proceed to implement a simple feed forward neural network. Next you will master optimization techniques and algorithms for neural networks using TensorFlow. Further, you will learn to implement some more complex types of neural networks such as convolutional neural networks, recurrent neural networks, and Deep Belief Networks. In the course of the book, you will be working on real-world datasets to get a hands-on understanding of neural network programming. You will also get to train generative models and will learn the applications of autoencoders. By the end of this book, you will have a fair understanding of how you can leverage the power of TensorFlow to train neural networks of varying complexities, without any hassle. While you are learning about various neural network implementations you will learn the underlying mathematics and linear algebra and how they map to the appropriate TensorFlow constructs.

Who is this book for?

This book is meant for developers with a statistical background who want to work with neural networks. Though we will be using TensorFlow as the underlying library for neural networks, book can be used as a generic resource to bridge the gap between the math and the implementation of deep learning.

Wishing to learn about TensorFlow, I decided to survey TF books available from Amazon, and pick one or two for further study. I excluded self-published offerings, and ended up with this longish list, dominated by Packt titles:"Machine Learning with TensorFlow" by Shukla, published by Manning in 2018-02, 272 pp, $43"Mastering TensorFlow 1.x" by Fandango, Packt, 2018-01, 474 pp, $35"Pro Deep Learning with TensorFlow" by Pattanayak, Apress, 2017-12, 398 pp, $37"TensorFlow 1.x Deep Learning Cookbook" by Gulli and Kapoor, Packt, 2017-12, 536 pp, $32"Neural Network Programming with TensorFlow" by Ghotra and Dua, Packt, 2017-11, 274 pp, $40"Predictive Analytics with TensorFlow" by Karim, Packt, 2017-11, 522 pp, $50"Machine Learning with TensorFlow 1.x" by Hua and Azeem, Packt, 2017-11, 304 pp, $39"Learning TensorFlow" by Hope and Resheff, O'Reilly, 2017-08, 242 pp, $25"Hands-On Deep Learning with TensorFlow" by Van Boxel, Packt, 2017-07, 174 pp, $35"Deep Learning with TensorFlow" by Zaccone, Karim, Menshawy, Packt, 2017-04, 320 pp, $50"TensorFlow Machine Learning Cookbook" by McClure, Packt, 2017-02, 370 pp, $30"Building Machine Learning Projects with TensorFlow" by Bonnin, Packt, 2016-11, 291 pp, $35"Getting Started with TensorFlow" by Zaccone, Packt, 2016-07, 180 pp, $35I reviewed the doc on tensorflow.org - including the doc for older releases - then started looking at books. One week later, I am still not done, but have winnowed out some options. The books by Van Boxel and Zaccone are out - these are brief (and not up-to-date) introductions, costing as much as more substantial titles. The books by Karim, and by Zacone and Karim, are out as a matter of principle, or of my personal distaste for plagiarism. The book by Bonnin offers unremarkable content spoiled by remarkably poor English and a myriad of typos - out."Neural Network Programming with TensorFlow" is the next casualty. I have read only a few pages, and, oh boy, I don't want to go further - it's really poor, I-am-concerned-about-authors'-sanity poor. (Yes, I am talking about that "Environment setup" section in the middle of "Linear algebra" (!) chapter. The only other pages I have glimpsed were the table of contents, and it resembled Karim's). Call me trigger-happy, but I believe in cutting losses early. Moving on…

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.
