Ancient Greek characters (AL-PUB)

The App's on-device Greek character model was developed using the AL-PUB dataset of labelled Greek characters from published Oxyrhynchus papyri, created through the Ancient Lives citizen-science project:

Swindall, M. I., Croisdale, G., Hunter, C. C., Keener, B., Williams, A. C., Brusuelas, J. H., Krevans, N., Sellew, M., Fortson, L., & Wallin, J. F. (2021).
