Overview of this book

Are you fascinated by how deep learning powers intelligent applications such as self-driving cars, virtual assistants, facial recognition devices, and chatbots to process data and solve complex problems? Whether you are familiar with machine learning or are new to this domain, The Deep Learning Workshop will make it easy for you to understand deep learning with the help of interesting examples and exercises throughout. The book starts by highlighting the relationship between deep learning, machine learning, and artificial intelligence and helps you get comfortable with the TensorFlow 2.0 programming structure using hands-on exercises. You’ll understand neural networks, the structure of a perceptron, and how to use TensorFlow to create and train models. The book will then let you explore the fundamentals of computer vision by performing image recognition exercises with convolutional neural networks (CNNs) using Keras. As you advance, you’ll be able to make your model more powerful by implementing text embedding and sequencing the data using popular deep learning solutions. Finally, you’ll get to grips with bidirectional recurrent neural networks (RNNs) and build generative adversarial networks (GANs) for image synthesis. By the end of this deep learning book, you’ll have learned the skills essential for building deep learning models with TensorFlow and Keras.

Preface

Making Predictions on Unseen Data

Now that you've trained your model on some data and assessed its performance on the test data, the next thing is to learn how to use this model to predict the sentiment for new data. That is the purpose of the model, after all – being able to predict the sentiment for data previously unseen by the model. Essentially, for any new review in the form of raw text, we should be able to classify its sentiment.

The key step for this would be to create a process/pipeline that converts the raw text into a format the predictive model understands. This would mean that the new text would need to undergo exactly the same preprocessing steps that were performed on the text data that was used to train the model. The function for preprocessing needs to return formatted text for any input raw text. The complexity of this function depends on the steps performed on the train data. If tokenization was the only preprocessing step performed, then the function...
