- Type: TableOriginal DataThe original nominal column and possibly dependency columns
This component generates synthetic values into a nominal column based on the frequency distribution of the original nominal column. It’s also possible to generate synthetic data based on the multivariate frequency distribution of the nominal column and one or more dependency columns. The synthetic value of each row in the original data can be recognized by the row ID. In addition, it is possible to exclude too few original examples from the data generation, and add random noise to the synthetic data. Synthetic data generation is used, for example, when the original data is confidential (anonymization) or difficult or expensive to collect.
- Type: TableSynthetic DataThe synthetic nominal column together with the original row IDs
- Type: TableStatistics TableThe frequency distribution of the original nominal column and possibly the dependency columns
- Type: TableInput Data Dependency Group MappingThe dependency group ID of each row ID in the original data
