Research Experience
Currently a researcher at Preferred Networks, focusing on machine learning for healthcare and quantum chemistry domains.
Education
Completed a PhD under the supervision of Prof. Masashi Sugiyama in the Sugiyama-Yokoya-Ishida laboratory, Department of Computer Science, The University of Tokyo. His doctoral thesis was titled 'Theory and algorithms of machine learning with rejection based on loss function perspective.'
Background
Research interests include machine learning algorithm analysis and design, specifically in loss functions, evaluation metrics, learning with a reject option, weakly supervised learning, domain adaptation, anomaly detection, and uncertainty quantification. Applications include healthcare data analysis, neural network potentials for quantum chemistry, speech signal processing, computer vision, and natural language processing.
