3.10.1 Anomaly Detection Model Types

There are two types of anomaly detection types: unsupervised and semi-supervised.

Unsupervised Anomaly Detection

When running an unsupervised anomaly detection model the machine learning algorithm requires no labeled data. When training the model, the target_column_name parameter must be set to NULL.

Semi-supervised Anomaly Detection

MySQL 9.0.1-u1 introduces support for semi-supervised learning. This type of machine learning algorithm uses a specific set of labeled data along with unlabeled data to detect anomalies. To enable this, use the experimental and semisupervised options. The target_column_name parameter must specify a column whose only allowed values are 0, 1, and NULL. All rows will be used to train the unsupervised component, while the rows with a value different than NULL will be used to train the supervised component.
