Everything we have written up formally. All of it is on the open web, and none of it is behind a publisher.

    Frequency-Stratified Evaluation for Long-Tail Multi-Label Tagging

    Ashish Kumar, Rin Amagai

    Sample entry. We argue that aggregate F1 over a long-tail label vocabulary systematically hides tail collapse, propose a frequency-stratified reporting protocol, and show that three published taggers reverse rank order under it.

    Region-Conditioned Flow Matching for Controllable Illustration Synthesis

    Ashish Kumar, Kaede Morii

    Sample entry. Treating spatial masks as a training-time conditioning signal rather than a sampling-time edit produces composition control that survives short sampling schedules.

    Aurora: An Auditable Pipeline for Large Illustration Corpora

    Ashish Kumar, Yuki Hoshino

    Sample entry. A description of the crawl, dedup, annotation and quality-banding passes behind the Aurora corpus, published with the filter configurations so that every exclusion can be reproduced or disputed.
