Haruki Sakajo
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, interpretability, and efficient/low-resource methods.
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.
