Occasionally an existing rule needs to be retrained. This sometimes happens when a rule is not detecting all the duplicates or a large amount of new data has been added to Salesforce.
Notice that an existing rule has a version number. To re-train this rule, select it from the list and press OPEN.
Then select the TRAIN button and CONFIRM to create a new version.
On the next screen, you are asked to evaluate if a pair of records is a duplicate. You can answer, Yes, No or Not Sure. The process is the same as training a new model, except the training picks up where the previous version stopped.
Press the Finish button to complete the re-training. Note that the a new version of the rule will be created.
Good to know: All the versions of a rule are available for selection by a dataset
