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.

Data model

The data model in TensorFlow is represented by tensors. Without using complex mathematical definitions, we can say that a tensor (in TensorFlow) identifies a multidimensional numerical array.

This data structure is characterized by three parameters--Rank, Shape, and Type.

Rank

Each tensor is described by a unit of dimensionality called rank. It identifies the number of dimensions of the tensor, for this reason, a rank is a known-as order or n-dimensions of a tensor. A rank zero tensor is a scalar, a rank one tensor ID a vector, while a rank two tensor is a matrix.

The following code defines a TensorFlow scalar, a vector, a matrix and a cube_matrix, in the next example we show how the rank works:

 
import tensorflow as tf

scalar = tf.constant(100)
vector...
