I am a graduate student doing research on machine learning.
My research interest lies in learning and inference from label-scarce, imbalanced, and unreliable data.
I am also interested in statistical learning theory and optimization.
I'm going to travel around Europe and give several talks from Sep. 6th until Sep. 23rd. I'll visit Brussels (6-8), Berlin (9-11), Paris (12-15), Edinburgh (16-18), London (19-21), and Lille (22-23). If you are there by chance, let's have a chat!
I started Ph.D. course from this April in UTokyo. When you visit Tokyo, please feel free to contact me.
