Mastering TensorFlow 1.x

Overview of this book

TensorFlow is the most popular numerical computation library built from the ground up for distributed, cloud, and mobile environments. TensorFlow represents the data as tensors and the computation as graphs. This book is a comprehensive guide that lets you explore the advanced features of TensorFlow 1.x. Gain insight into TensorFlow Core, Keras, TF Estimators, TFLearn, TF Slim, Pretty Tensor, and Sonnet. Leverage the power of TensorFlow and Keras to build deep learning models, using concepts such as transfer learning, generative adversarial networks, and deep reinforcement learning. Throughout the book, you will obtain hands-on experience with varied datasets, such as MNIST, CIFAR-10, PTB, text8, and COCO-Images. You will learn the advanced features of TensorFlow1.x, such as distributed TensorFlow with TF Clusters, deploy production models with TensorFlow Serving, and build and deploy TensorFlow models for mobile and embedded devices on Android and iOS platforms. You will see how to call TensorFlow and Keras API within the R statistical software, and learn the required techniques for debugging when the TensorFlow API-based code does not work as expected. The book helps you obtain in-depth knowledge of TensorFlow, making you the go-to person for solving artificial intelligence problems. By the end of this guide, you will have mastered the offerings of TensorFlow and Keras, and gained the skills you need to build smarter, faster, and efficient machine learning and deep learning systems.

CNN architecture pattern - LeNet

LeNet is a popular architectural pattern for implementing CNN. In this chapter, we shall learn to build CNN model based on LeNet pattern by creating the layers in the following sequence:

  1. The input layer
  2. The convolutional layer 1 that produces a set of feature maps, with ReLU activation
  3. The pooling layer 1 that produces a set of statistically aggregated feature maps
  4. The convolutional layer 2 that produces a set of feature maps, with ReLU activation
  5. The pooling layer 2 that produces a set of statistically aggregated feature maps
  6. The fully connected layer that flattens the feature maps, with ReLU activation
  7. The output layer that produces the output by applying simple linear activation
LeNet family of models were introduced by Yann LeCun and his fellow researchers. More details on the LeNet family of models can be found at the following link: http...
