Gretel Evaluation

Gretel.ai is another tool that provides the functionality to generate synthetic tabular data. We also use their Gretel Score as an evaluation metric.

Installing Gretel Client

pip install gretel-client

If you are using Jupyter Notebook or Google Colab, please restart your kernel after installing the package.

from sdgne.evaluator.evaluator import GretelEvaluation

evaluator = GretelEvaluation(synthesized_data, minority_column_label, 
                                minority_class_label, gretel_api_key)
                                
report = evaluator.run_gretel_quality_report()

Importing Gretel Evaluation

from sdgne.evaluator.evaluator import GretelEvaluation

Creating an evaluator

report = evaluator.run_gretel_quality_report()   

Return

A dictionary containing the quality report generated by Gretel AI [7].

To generate Gretel Score for synthetic data using SDGnE, you'd require Gretel API Key.
