Machine Learning with TensorFlow 1.x

By: Quan Hua, Saif Ahmed, Shams Ul Azeem

Overview of this book

Google's TensorFlow is a game changer in the world of machine learning. It has made machine learning faster, simpler, and more accessible than ever before. This book will teach you how to easily get started with machine learning using the power of Python and TensorFlow 1.x. Firstly, you’ll cover the basic installation procedure and explore the capabilities of TensorFlow 1.x. This is followed by training and running the first classifier, and coverage of the unique features of the library including data ?ow graphs, training, and the visualization of performance with TensorBoard—all within an example-rich context using problems from multiple industries. You’ll be able to further explore text and image analysis, and be introduced to CNN models and their setup in TensorFlow 1.x. Next, you’ll implement a complete real-life production system from training to serving a deep learning model. As you advance you’ll learn about Amazon Web Services (AWS) and create a deep neural network to solve a video action recognition problem. Lastly, you’ll convert the Caffe model to TensorFlow and be introduced to the high-level TensorFlow library, TensorFlow-Slim. By the end of this book, you will be geared up to take on any challenges of implementing TensorFlow 1.x in your machine learning environment.

Using the classifier

Now that we've enhanced the classifier to load random images, we'll start with choosing these random images with the exact size and shape of our training/testing images. We'll need to add placeholders for these user-provided images, so we'll add the following lines in the appropriate locations:

 tf_random_dataset = tf.placeholder(tf.float32, shape=(1, 
image_size, image_size, num_channels),
name='RANDOM_DATA')random_prediction =
tf.nn.softmax(nn_model(tf_random_dataset,
weights, biases))

Next, we will grab the image provided by the user via the following command-line parameter and run our session on the image:

We will follow almost the exact sequence as we did earlier. Running a test file through the script using the -e switch will yield an extra output, as follows:

    The prediction is: 2 

Voila! We just classified an...
