Create machine learning models in BigQuery ML

Create machine learning models in BigQuery ML

This tutorial shows you how to create a logistic regression model by using BigQuery ML in the Google Cloud console.

BigQuery ML lets you create and train machine learning models in BigQuery by using SQL queries. This helps make machine learning more approachable by letting you use familiar tools like the BigQuery SQL editor, and also increases development speed by removing the need to move data into a separate machine learning environment.

In this tutorial, you use the sample Google Analytics sample dataset for BigQuery to create a model that predicts whether a website visitor will make a transaction. For information on the schema of the Analytics dataset, see BigQuery export schema in the Analytics Help Center.

Objectives

This tutorial shows you how to perform the following tasks:

• Using the CREATE MODEL statement to create a binary logistic regression model.
• Using the ML.EVALUATE function to evaluate the model.
• Using the ML.PREDICT function to make predictions by using the model.

Costs

This tutorial uses billable components of Google Cloud, including the following:

• BigQuery
• BigQuery ML

     The public datasets are stored in the US multi-region. For simplicity, store your dataset in the same location.

   • Leave the remaining default settings as they are, and click Create dataset.

     

Create a logistic regression model

Create a logistic regression model using the Analytics sample dataset for BigQuery.

SQL

1. In the Google Cloud console, go to the BigQuery page.

   Go to BigQuery

2. In the query editor, run the following statement:

   CREATE OR REPLACE MODEL `bqml_tutorial.sample_model`
   OPTIONS(model_type='logistic_reg') AS
   SELECT
   IF(totals.transactions IS NULL, 0, 1) AS label,
   IFNULL(device.operatingSystem, "") AS os,
   device.isMobile AS is_mobile,
   IFNULL(geoNetwork.country, "") AS country,
   IFNULL(totals.pageviews, 0) AS pageviews
   FROM
   `bigquery-public-data.google_analytics_sample.ga_sessions_*`
   WHERE
   _TABLE_SUFFIX BETWEEN '20160801' AND '20170630'
   

   The query takes several minutes to complete. After the first iteration is complete, your model (sample_model) appears in the navigation panel. Because the query uses a CREATE MODEL statement to create a model, you don't see query results.

Query details

The CREATE MODEL statement creates the model and then trains the model using the data retrieved by your query's SELECT statement.

The OPTIONS(model_type='logistic_reg') clause creates a logistic regression model. A logistic regression model splits input data into two classes, and then estimates the probability that the data is in one of the classes. What you are trying to detect, such as whether an email is spam, is represented by 1 and other values are represented by 0. The likelihood of a given value belonging to the class you are trying to detect is indicated by a value between 0 and 1. For example, if an email receives a probability estimate of 0.9, then there is a 90% probability that the email is spam.

This query's SELECT statement retrieves the following columns that are used by the model to predict the probability that a customer will complete a transaction:

• totals.transactions: the total number of ecommerce transactions within the session. If the number of transactions is NULL, the value in the label column is set to 0. Otherwise, it is set to 1. These values represent the possible outcomes. Creating an alias named label is an alternative to setting the input_label_cols= option in the CREATE MODEL statement.
• device.operatingSystem: the operating system of the visitor's device.
• device.isMobile — Indicates whether the visitor's device is a mobile device.
• geoNetwork.country: the country from which the sessions originated, based on the IP address.
• totals.pageviews: the total number of page views within the session.

The FROM clause — causes the query to train the model by using the bigquery-public-data.google_analytics_sample.ga_sessions sample tables. These tables are sharded by date, so you aggregate them by using a wildcard in the table name: google_analytics_sample.ga_sessions_*.

The WHERE clause — _TABLE_SUFFIX BETWEEN '20160801' AND '20170630' — limits the number of tables scanned by the query. The date range scanned is August 1, 2016 to June 30, 2017.

View the model's loss statistics

Machine learning is about creating a model that can use data to make a prediction. The model is essentially a function that takes inputs and applies calculations to the inputs to produce an output — a prediction.

Machine learning algorithms work by taking several examples where the prediction is already known (such as the historical data of user purchases) and iteratively adjusting various weights in the model so that the model's predictions match the true values. It does this by minimizing how wrong the model is using a metric called loss.

The expectation is that for each iteration, the loss should be decreasing, ideally to zero. A loss of zero means the model is 100% accurate.

When training the model, BigQuery ML automatically splits the input data into training and evaluation sets, in order to avoid overfitting the model. This is necessary so that the training algorithm doesn't fit itself so closely to the training data that it can't generalize to new examples.

Use the Google Cloud console to see how the model's loss changes over the model's training iterations:

1. In the Google Cloud console, go to the BigQuery page.

   Go to BigQuery

2. In the Explorer pane, expand bqml_tutorial > Models and then click sample_model.

3. Click the Training tab and look at the Loss graph. The Loss graph shows the change in the loss metric over the iterations on the training dataset. If you hold your cursor over the graph, you can see that there are lines for Training loss and Evaluation loss. Since you performed a logistic regression, the training loss value is calculated as log loss, using the training data. The evaluation loss is the log loss calculated on the evaluation data. Both loss types represent average loss values, averaged over all examples in the respective datasets for each iteration.

You can also see the results of the model training by using the ML.TRAINING_INFO function.

Evaluate the model

Evaluate the performance of the model by using the ML.EVALUATE function. The ML.EVALUATE function evaluates the predicted values generated by the model against the actual data. To calculate logistic regression specific metrics, you can use the ML.ROC_CURVE SQL function or the bigframes.ml.metrics.roc_curve BigQuery DataFrames function.

In this tutorial, you are using a binary classification model that detects transactions. The values in the label column are the two classes generated by the model: 0 (no transactions) and 1 (transaction made).

SQL

1. In the Google Cloud console, go to the BigQuery page.

   Go to BigQuery

2. In the query editor, run the following statement:

   SELECT
   *
   FROM
   ML.EVALUATE(MODEL `bqml_tutorial.sample_model`, (
   SELECT
   IF(totals.transactions IS NULL, 0, 1) AS label,
   IFNULL(device.operatingSystem, "") AS os,
   device.isMobile AS is_mobile,
   IFNULL(geoNetwork.country, "") AS country,
   IFNULL(totals.pageviews, 0) AS pageviews
   FROM
   `bigquery-public-data.google_analytics_sample.ga_sessions_*`
   WHERE
   _TABLE_SUFFIX BETWEEN '20170701' AND '20170801'))
   

   The results should look like the following:

     +--------------------+---------------------+---------------------+---------------------+---------------------+--------------------+
     |     precision      |       recall        |      accuracy       |      f1_score       |      log_loss       | roc_auc                   |
     +--------------------+---------------------+---------------------+---------------------+---------------------+--------------------+
     | 0.468503937007874  | 0.11080074487895716 | 0.98534315834767638 | 0.17921686746987953 | 0.04624221101176898    | 0.98174125874125873 |
     +--------------------+---------------------+---------------------+---------------------+---------------------+--------------------+
     

   Because you performed a logistic regression, the results include the following columns:

   • precision: a metric for classification models. Precision identifies the frequency with which a model was correct when predicting the positive class.

   • recall: a metric for classification models that answers the following question: Out of all the possible positive labels, how many did the model correctly identify?

   • accuracy: accuracy is the fraction of predictions that a classification model got right.

   • f1_score: a measure of the accuracy of the model. The f1 score is the harmonic average of the precision and recall. An f1 score's best value is 1. The worst value is 0.

   • log_loss: the loss function used in a logistic regression. This is the measure of how far the model's predictions are from the correct labels.

   • roc_auc: the area under the ROC curve. This is the probability that a classifier is more confident that a randomly chosen positive example is actually positive than that a randomly chosen negative example is positive. For more information, see Classification in the Machine Learning Crash Course.

Query details

The initial SELECT statement retrieves the columns from your model.

The FROM clause uses the ML.EVALUATE function against your model.

The nested SELECT statement and FROM clause are the same as those in the CREATE MODEL query.

The WHERE clause — _TABLE_SUFFIX BETWEEN '20170701' AND '20170801' — limits the number of tables scanned by the query. The date range scanned is July 1, 2017 to August 1, 2017. This is the data you're using to evaluate the predictive performance of the model. It was collected in the month immediately following the time period spanned by the training data.

SQL

1. In the Google Cloud console, go to the BigQuery page.

   Go to BigQuery

2. In the query editor, run the following statement:

   SELECT
   country,
   SUM(predicted_label) as total_predicted_purchases
   FROM
   ML.PREDICT(MODEL `bqml_tutorial.sample_model`, (
   SELECT
   IFNULL(device.operatingSystem, "") AS os,

Query details

The initial SELECT statement retrieves the country column and sums the predicted_label column. The predicted_label column is generated by the ML.PREDICT function. When you use the ML.PREDICT function, the output column name for the model is predicted_<label_column_name>. For linear regression models, predicted_label is the estimated value of label. For logistic regression models, predicted_label is the label that best describes the given input data value, either 0 or 1.

The ML.PREDICT function is used to predict results using your model.

The nested SELECT statement and FROM clause are the same as those in the CREATE MODEL query.

The WHERE clause — _TABLE_SUFFIX BETWEEN '20170701' AND '20170801' — limits the number of tables scanned by the query. The date range scanned is July 1, 2017 to August 1, 2017. This is the data for which you're making predictions. It was collected in the month immediately following the time period spanned by the training data.

The GROUP BY and ORDER BY clauses group the results by country and order them by the sum of the predicted purchases in descending order.

The LIMIT clause is used here to display only the top 10 results.

Clean up

To avoid incurring charges to your Google Cloud account for the resources used on this page, follow these steps.

You can delete the project you created, or keep the project and delete the dataset.

Delete the dataset

Deleting your project removes all datasets and all tables in the project. If you prefer to reuse the project, you can delete the dataset you created in this tutorial:

1. In the Google Cloud console, go to the BigQuery page.

   Go to BigQuery

2. In the Explorer pane, select the bqml_tutorial dataset you created.

3. Click Actions > Delete.

4. In the Delete dataset dialog, confirm the delete command by typing delete.

5. Click Delete.

Delete the project

To delete the project:

Caution: Deleting a project has the following effects:

• Everything in the project is deleted. If you used an existing project for the tasks in this document, when you delete it, you also delete any other work you've done in the project.
• Custom project IDs are lost. When you created this project, you might have created a custom project ID that you want to use in the future. To preserve the URLs that use the project ID, such as an appspot.com URL, delete selected resources inside the project instead of deleting the whole project.

If you plan to explore multiple architectures, tutorials, or quickstarts, reusing projects can help you avoid exceeding project quota limits.

1. In the Google Cloud console, go to the Manage resources page.

   Go to Manage resources

2. In the project list, select the project that you want to delete, and then click Delete.
3. In the dialog, type the project ID, and then click Shut down to delete the project.
