Research direction
Review existing transformers in the TransmogrifAI codebase (e.g., in the 'transformers' package) to understand the required interface and naming conventions. Implement a new 'GeolocationToCountry' transformer that converts Geolocation features to a categorical country feature. Consider using a lightweight reverse geocoding library or a preloaded dataset, ensuring compatibility with Apache Spark's distributed computing. Check if there are any related open issues or discussions in the repository for additional context.
