Generates the matching model that is used by the tMatchPredict component to automatically predict the labels for the suspect pairs and groups records which match the label(s) set in the component properties.
For further information about the tMatchPairing and tMatchPredict components, see tMatchPairing and tMatchPredict respectively.
tMatchModel reads the sample of the suspect pairs outputted by tMatchPairing after you label each second element in a pair, analyzes the data using the Random Forest algorithm and generates a matching model.
You can use the sample suspect records labeled in a Grouping campaign defined in Talend Data Stewardship with tMatchModel.
In local mode, Apache Spark 2.4.0 and later versions are supported.
This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.
