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.

Test and translate

The code for the translation is in the file test_translator.py.

We start with some imports and the location of the pre-trained model:

import pickle
import sys
import numpy as np
import tensorflow as tf
import data_utils
from train_translator import (get_seq2seq_model, path_l1_dict, path_l2_dict,
build_dataset)
model_dir = "/tmp/translate"

Now, let's create a function to decode the output sequence generated by the RNN. Mind that the sequence is multidimensional, and each dimension corresponds to the probability of that word, therefore we will pick the most likely one. With the help of the reverse dictionary, we can then figure out what was the actual word. Finally, we will trim the markings (padding, start, end of string) and print the output.

In this example, we will decode the first five sentences in the training set, starting from the raw corpora....
