Machine Learning with BigQuery ML

By: Alessandro Marrandino

Overview of this book

BigQuery ML enables you to easily build machine learning (ML) models with SQL without much coding. This book will help you to accelerate the development and deployment of ML models with BigQuery ML. The book starts with a quick overview of Google Cloud and BigQuery architecture. You'll then learn how to configure a Google Cloud project, understand the architectural components and capabilities of BigQuery, and find out how to build ML models with BigQuery ML. The book teaches you how to use ML using SQL on BigQuery. You'll analyze the key phases of a ML model's lifecycle and get to grips with the SQL statements used to train, evaluate, test, and use a model. As you advance, you'll build a series of use cases by applying different ML techniques such as linear regression, binary and multiclass logistic regression, k-means, ARIMA time series, deep neural networks, and XGBoost using practical use cases. Moving on, you'll cover matrix factorization and deep neural networks using BigQuery ML's capabilities. Finally, you'll explore the integration of BigQuery ML with other Google Cloud Platform components such as AI Platform Notebooks and TensorFlow along with discovering best practices and tips and tricks for hyperparameter tuning and performance enhancement. By the end of this BigQuery book, you'll be able to build and evaluate your own ML models with BigQuery ML.

Summary

In this chapter, we built our first machine learning use case based on a real-life scenario. After a brief introduction to the use case, we discovered what linear regression is and how it can be used to predict numerical values.

Before diving into actually developing the machine learning model, we learned that having a clear understanding of the data and checking its quality is fundamental to getting effective machine learning models. To start from a solid foundation, we leveraged the BigQuery public dataset, which collects information about all the rentals for a bike sharing service in New York City.

For training the model, we used different features to understand which variables are relevant to building our BigQuery ML model.

Then, we chose one machine learning model to carry on to the evaluation stage. In this phase, we used the BigQuery evaluation function to verify that the machine learning model could also effectively work on new rows outside the training dataset...
