Selfie taken in Tokyo, November 2018.

I am a PhD student under the supervision of Prof. Masashi Sugiyama in Sugiyama-Sato-Honda laboratory, Department of computer science, The University of Tokyo.

Research interests: I am interested in machine learning algorithm analysis and design in general. More specifically, my current research topics include:

Loss function
Learning with reject option
Weakly-supervised learning
Domain adaptation

Jan 14, 2020	I participated in the Global Young Scientists Summit 2020 in Singapore (14-17 Jan). I also gave a poster presentation of my master’s thesis “Machine learning from Noisy Labels: An Approach Based on Symmetric Losses”.
Nov 12, 2019	I gave an oral presentation: “Symmetric Loss and Its Applications to Learning under Label Noise” in Focus Program on Data Science and Optimization: Conference on Data Science at The Fields Institute, Toronto, Canada. The content was about our ICML2019 and EMNLP-IJCNLP2019 papers.
Nov 10, 2019	Our paper: “Classification from Triplet Comparison Data” has been accepted to Neural Computation.
Oct 21, 2019	I wrote about the project I did in PFN as an intern which is “Open-set Few-shot Speaker Identification”, in Preferred Networks Research Blog. I am really grateful to my mentors: Yuta Tsuboi and Katsuhiko Ishiguro, as well as other members in the team. Also, it is my pleasure to meet other interns and to have a chance to enjoy the internship program together!
