Affiliation: 3rd year, Department of Information and Social Sciences, Faculty of Informatics, Shizuoka University
Born: 2004, Ishikawa

I am currently studying informatics at university. I am particularly interested in the mathematical understanding of language and intelligence (statistical/geometric/information-theoretic analysis). Among these, I am also interested in symbol emergence and language emergence. I believe in the value of implementing theory in society.
