Ph.D. student @ Kyushu Institute of Technology | [email protected]

I am a Ph.D. student of Shimada Laboratory in the Department of Artificial Intelligence at Kyushu Institute of Technology (Kyutech), Fukuoka, Japan, conducting research in Natural Language Processing advised by Prof. Kazutaka SHIMADA. Prior to this, I did my masters in RAI lab at KMITL in Bangkok, Thailand.

My current research interests lie in active learning and multi-task learning in code-mixed data.
