Shuhei M. YOSHIDA, PhD

Researcher in machine learning and computer vision

Biometrics Research Laboratories, NEC Corporation

RIKEN AIP-NEC Collaboration Center

I am a researcher in machine learning and computer vision at Biometrics Research Laboratories, NEC Corporation, and a visiting researcher at RIKEN AIP. My main research interest is in the field of machine learning algorithms that work with limited supervision, such as weakly supervised learning and transfer learning.

I got my Ph. D. in physics at The University of Tokyo. The theme of my Ph. D. study was universality in strongly correlated quantum gases and few-body systems.

“Shuhei Yoshida” is such a common name that I once met a guy with the name in an physics conference! Please don’t confuse me with other “Shuhei Yoshida”. Most of my publications in English have the middle initial “M” in my name.

Volunteer staff & TA

Non-Profit Organization “Wings for Mathematical Science” (数理の翼)

The NPO organizes summer / winter schools for science-oriented high-school students. I participated in the executive committees for the 32nd (2011), 34th (2013), and 35th (2014) Summer Seminar as a volunteer staff, a TA, and the Vice-Chairperson, respectively. I also organized the One-Day Workshop in 2009, the 2nd Winter Seminar (2010), the Okawa Seminars in 2010, 2011, and 2013 as a volunteeer staff.
