I am Haruki Sakajo (坂上 温紀), a PhD student at Nara Institute of Science and Technology
(NAIST). I am interested in Computational Linguistics, Low-Resource Natural Language Processing, and
Multimodal/Multilingual Language Models. I am also interested in
linguistics and historical documents.
I aim to analyze the behavior of language models from various perspectives and granularities, and use the insights to contribute to the development of language models and their applications.
