Overview of this book

TensorFlow is one of the most popular frameworks used for machine learning and, more recently, deep learning. It provides a fast and efficient framework for training different kinds of deep learning models, with very high accuracy. This book is your guide to master deep learning with TensorFlow with the help of 10 real-world projects. TensorFlow Deep Learning Projects starts with setting up the right TensorFlow environment for deep learning. You'll learn how to train different types of deep learning models using TensorFlow, including Convolutional Neural Networks, Recurrent Neural Networks, LSTMs, and Generative Adversarial Networks. While doing this, you will build end-to-end deep learning solutions to tackle different real-world problems in image processing, recommendation systems, stock prediction, and building chatbots, to name a few. You will also develop systems that perform machine translation and use reinforcement learning techniques to play games. By the end of this book, you will have mastered all the concepts of deep learning and their implementation with TensorFlow, and will be able to build and train your own deep learning models with TensorFlow confidently.

Image captioning approaches

There are several approaches to captioning images. Earlier methods used to construct a sentence based on the objects and attributes present in the image. Later, recurrent neural networks (RNN) were used to generate sentences. The most accurate method uses the attention mechanism. Let's explore these techniques and results in detail in this section.

Conditional random field

Initially a method was tried with the conditional random field (CRF) constructing the sentence with the objects and attributes detected in the image. The steps involved in this process are shown as follows:
