Yandere2023: A Large-Scale Crowdsourced and Tagged Anime Illustration Dataset

Yandere2023 is a comprehensive anime image dataset with over 1.2 million high-quality images sourced from various materials, including key frames, manga scans, artbooks, and more. While the average number of tags per image is relatively low, the dataset boasts a diverse collection of images with exceptional quality.

Uses

Format

The goal of the dataset is to be as easy as possible to use immediately, avoiding obscure file formats, while allowing simultaneous research & seeding of the torrent, with easy updates.

Images are provided in the full original form (be that JPG, PNG, GIF or otherwise) for reference/archival purposes, and bucketed into 1000 subdirectories 0000–0999 (0-padded), which is the Yandere ID modulo 1000 (ie. all images in 0999/ have an ID ending in β€˜999’); IDs can be turned into paths by dividing & padding (eg. in Bash, BUCKET=$(printf "%04d" $(( ID % 1000 )) )) and then the file is at original/$BUCKET/$ID.$EXT.

The reason for the bucketing is that a single directory would cause pathological filesystem performance, and modulo ID is a simple hash which spreads images evenly without requiring additional future directories to be made or a filesystem IO to check where the file is. The ID is not zero-padded and files end in the relevant extension, hence the file layout looks like this:
