Hello, I am Haruki Sakajo

I am Haruki Sakajo (坂上 温紀), a master's 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 I am also interested in linguistics and historical documents.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.
