Contributed to the modelscope/data-juicer repository by enhancing data ingestion and deduplication workflows over a two-month period. Developed support for loading compressed JSON and JSONL files in Ray datasets, expanding compatibility with .gz and .zst formats and streamlining data pipelines. Improved format recognition and extended the JsonFormatter to handle new file types, reducing preprocessing time and optimizing storage. Addressed a critical bug in the MinHash-based deduplication pipeline, ensuring all duplicates are accurately matched and recorded to strengthen data integrity. Leveraged Python, algorithm optimization, and unit testing to deliver robust, maintainable solutions that improved reliability and efficiency in data processing.
