I am working at the Aizawa-Yamakata-Matsui Lab as a Postdoc. I am interested in computer vision, multimedia processing, and data-centric AI. I have conducted OCR tasks such as multilingual text recognition and synthetic visual text generation. Currently, I am learning/focusing on large language models (LLMs) and large multimodal models (LMMs).
