Retraining a Trainable Classifier

C.

If you are unsatisfied with the result of a trainable classifier for a sensitive information type, you can retrain the classifier to improve its accuracy. To do this, you will need to use the content explorer from Data classification in the Microsoft 365 compliance center.

Content explorer is a tool that allows you to analyze and manage the data in your organization. You can use it to identify sensitive information types based on predefined templates or to create your own trainable classifiers.

To retrain the classifier, you will need to follow these steps:

1. Go to the Microsoft 365 compliance center and select the Data classification option.
2. From the left pane, select Content explorer.
3. In the Content explorer window, select the sensitive information type that you want to retrain the classifier for.
4. Click on the "Train" button to open the trainable classifier editor.
5. Review the existing training data and add new examples or modify existing ones as necessary.
6. Once you have made the necessary changes, click on the "Train" button to retrain the classifier.
7. After the classifier has been retrained, you can test its accuracy by running a content search or using labels from information protection to classify data.

In summary, to retrain a trainable classifier for a sensitive information type, you will need to use the content explorer from Data classification in the Microsoft 365 compliance center.
