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.

Evaluating the matrix factorization model

In this section, we'll evaluate the performances of the matrix factorization model that we trained in the previous section.

The evaluation stage of a matrix factorization model can be performed using the ML.EVALUATE BigQuery ML function or through the BigQuery UI.

Let's execute the following query to extract all the evaluation parameters that characterize the recommendation model that we've just trained:

SELECT
  *
FROM
  ML.EVALUATE(MODEL `09_recommendation_engine.recommender`,
    (
    SELECT * FROM `09_recommendation_engine.product_visits`));

The result of this query is shown in the following screenshot:

The same information can be accessed by selecting the ML model from the BigQuery navigation menu and then accessing...
