Deep Learning with TensorFlow

Overview of this book

Deep learning is the step that comes after machine learning, and has more advanced implementations. Machine learning is not just for academics anymore, but is becoming a mainstream practice through wide adoption, and deep learning has taken the front seat. As a data scientist, if you want to explore data abstraction layers, this book will be your guide. This book shows how this can be exploited in the real world with complex raw data using TensorFlow 1.x. Throughout the book, you’ll learn how to implement deep learning algorithms for machine learning systems and integrate them into your product offerings, including search, image recognition, and language processing. Additionally, you’ll learn how to analyze and improve the performance of deep learning models. This can be done by comparing algorithms against benchmarks, along with machine intelligence, to learn from the information and determine ideal behaviors within a specific context. After finishing the book, you will be familiar with machine learning techniques, in particular the use of TensorFlow for deep learning, and will be ready to apply your knowledge to research or commercial projects.

Computational graphs

When performing an operation, for example training a neural network, or the sum of two integers, TensorFlow internally represent, its computation using a data flow graph (or computational graph).

This is a directed graph consisting of the following:

  • A set of nodes, each one representing an operation
  • A set of directed arcs, each one representing the data on which the operations are performed

TensorFlow has two types of edge:

  • Normal: They are only carriers of data structures, between the nodes. The output of one operation (from one node) becomes the input for another operation. The edge connecting two nodes carry the values.
  • Special: This edge doesn't carry values. It represents a control dependency between two nodes A and B. It means that the node B will be executed only if the operation in A will be ended before the relationship between operations on the data.
