IC-VCO Preference

This is the preference configuration in the IC-VCO dataset package. It uses a Parquet metadata file plus images stored in the shared package-level images/ directory. Image references are relative paths from this split's metadata file to ../../images/<bucket>/....

Schema

• id: stable sample id.
• source_idx: source row index.
• prompt: user prompt text.
• chosen: preferred response.
• rejected: dispreferred response.
• images_file_names: [chosen_image, rejected_image], relative paths into the shared ../../images/<bucket>/ directories.
• chosen_response_spans: character spans in chosen.
• rejected_response_spans: character spans in rejected.

Response spans use zero-based character offsets with an exclusive end index.

Loading

from datasets import load_dataset

dataset = load_dataset("OPPOer/IC-VCO-Dataset", "preference")

For local repository training, scripts/train.sh defaults to the repo-root IC-VCO-Dataset package. The preference stage loads this configuration automatically.
