Research

Our research interest focuses on Multimedia Analysis and Artificial Intelligence. Examples of our research topics include image recognition, speech recognition and video retrieval. We are developing algorithms and systems on TSUBAME, the supercomputer at the Science Tokyo. We welcome researchers and students who are interested in learning frameworks such as deep learning, zero-shot/few-shot learning using large multimodal models across image, text, and speech domains.

井上研究室では、マルチメディア情報処理の分野で、画像認識・音声認識・映像検索などの人工知能技術に関する研究を実施しています。 大規模データを処理するためのアルゴリズムやシステムの開発では、東京科学大学のスーパーコンピューターTSUBAMEを活用しています。 深層学習やゼロショット学習などの学習方式や、人工知能を構築するためのデータ作成に興味のある研究者・学生を募集中です。
