Data-Juicer
Data-Juicer: Data processing software that provides modular operators to clean, synthesize, and analyze multimodal datasets for foundation model training and tuning.
Data-Juicer acts as an operating system for data processing in the foundation model lifecycle. It provides over 200 operators to clean, synthesize, and analyze text, image, audio, video, and multimodal data. Users construct reproducible pipelines using YAML files to perform tasks like deduplication, semantic chunking, and quality gating. The system scales from local laptops to thousand-node clusters via Ray. It integrates with tools like HuggingFace, ModelScope, S3, and HDFS, while supporting various data formats like JSONL. The project includes a natural-language refinement model called Juicer for structured outputs.
