About ULTIMA

ULTIMA Dataset is Uma Musume Labeled Text-Image Multimodal Alignment Dataset.

ULTIMA is a supervised dataset for fine-tuning of characters in Uma Musume: Pretty Derby.

It contains ~14K text-image pairs.

We manually processed the entire data. This is an essential fact even though it is assisted by a machine.

What we did is on Data Preprocessing.md.
Statistics about datset and abbreviations of Uma Musume are in statistics.md.
Pruned tag-clothes pairs are in prompts.md

Dataset Structure

We use a modularized file structure to distribute ULTIMA. The 14,460 images in ULTIMA are split into 73 folders, where each folder contains 200 images and a JSON file that these 200 images to their text and information.

These sub-folders have names part-0xxxx, and each image has a name which has a format, [quality]_[abbreviation]_[image number].png. The JSON file in a sub-folder has the same name as the sub-folder. Each image is a PNG file. The JSON file contains key-value pairs mapping image filenames to their prompts and aesthetic scores.

Data Instances

For example, below is the image of 01_agt_00007.png and its key-value pair in part-00000.json.

Data Metadata

To help you easily access prompts and other attributes of images without downloading all the Zip files, we include metadata table metadata.parquet for ULTIMA.

The shape of metadata.parquet is (14460, 8). We store these tables in the Parquet format because Parquet is column-based: you can efficiently query individual columns (e.g., texts) without reading the entire table.

Below are first three rows from metadata.parquet.
