Overview of this book

The independent recipes in Machine Learning Using TensorFlow Cookbook will teach you how to perform complex data computations and gain valuable insights into your data. Dive into recipes on training models, model evaluation, sentiment analysis, regression analysis, artificial neural networks, and deep learning - each using Google’s machine learning library, TensorFlow. This cookbook covers the fundamentals of the TensorFlow library, including variables, matrices, and various data sources. You’ll discover real-world implementations of Keras and TensorFlow and learn how to use estimators to train linear models and boosted trees, both for classification and regression. Explore the practical applications of a variety of deep learning architectures, such as recurrent neural networks and Transformers, and see how they can be used to solve computer vision and natural language processing (NLP) problems. With the help of this book, you will be proficient in using TensorFlow, understand deep learning from the basics, and be able to implement machine learning algorithms in real-world scenarios.

Introduction

In this chapter, we briefly demonstrate how to approach a binary classification problem using BoostedTreesClassifier. We will apply the technique to solve a realistic business problem using a popular educational dataset: predicting which customers are likely to cancel their bookings. The data for this problem – and several other business problems – comes in tabular format, and typically contains a mixture of different feature types: numeric, categorical, dates, and so on. In the absence of sophisticated domain knowledge, gradient boosting methods are a good first choice for creating an interpretable solution that works out of the box. In the next section, the relevant modeling steps will be demonstrated with code: data preparation, structuring into functions, fitting a model through the tf.estimator functionality, and interpretation of results.
