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've implemented two DNNs. We remembered the business scenario that was already introduced in Chapter 4, Predicting Numerical Values with Linear Regression. The use case was based on the need to predict the rental time for the New York City bike-sharing service. After that, we learned the basics of DNNs and the different activation functions that can be used to implement the neurons in a network.

We segmented the BigQuery public dataset into three different tables: one to host training data, the second one for the evaluation stage, and the last one to test our DNN model.

During the training phase of the BigQuery ML model, we tested two different activation functions, ReLU and CReLU, comparing the mean absolute error to find the best one.

After that, we evaluated our DNN models on a new set of records to prevent any overfitting and get more confident about the good quality of our BigQuery ML models.

Finally, we applied the model, based on the...
