Overview of this book

Getting to grips with tensors, deep learning, and neural networks can be intimidating and confusing for anyone, no matter their experience level. The breadth of information out there, often written at a very high level and aimed at advanced practitioners, can make getting started even more challenging. If this sounds familiar to you, The TensorFlow Workshop is here to help. Combining clear explanations, realistic examples, and plenty of hands-on practice, it’ll quickly get you up and running. You’ll start off with the basics – learning how to load data into TensorFlow, perform tensor operations, and utilize common optimizers and activation functions. As you progress, you’ll experiment with different TensorFlow development tools, including TensorBoard, TensorFlow Hub, and Google Colab, before moving on to solve regression and classification problems with sequential models. Building on this solid foundation, you’ll learn how to tune models and work with different types of neural network, getting hands-on with real-world deep learning applications such as text encoding, temperature forecasting, image augmentation, and audio processing. By the end of this deep learning book, you’ll have the skills, knowledge, and confidence to tackle your own ambitious deep learning projects with TensorFlow.

Preface

Classification Models

The goal of classification models is to classify data into distinct classes. For example, a spam filter is a classification model that aims to classify emails into "spam" (referring to unsolicited and unwanted email) or "ham" (a legitimate email). Spam filters are an example of a binary classifier since there are two classes. The input to the filter may include the content of the email, the email address of the sender, and the subject line, among other features, and the output will be the predicted class, spam or ham. Classification models can classify data into more than two distinct classes (known as multi-class classification) or classify data with multiple positive labels (known as multi-label classification).

There are several different algorithms that can be used for classification tasks. Some popular ones include logistic regression, decision trees, and ANNs. ANNs are a great choice for classification models since they can learn complex...
