The Institute of Statistical Mathematics (ISM) is a Japanese research institute founded in 1944 and a member institute of the Research Organization of Information and Systems, a university inter-university research institute corporation. It advances fundamental and applied research in statistical mathematics and works with universities, research organizations, and industry through collaborative projects. Its official website introduces researchers and laboratories, current research projects, publications, seminars, research meetings, public lectures, and procedures for joint research. The institute studies how to identify structure behind real-world phenomena and data, and how to make sound inferences and decisions under uncertainty. The site also presents work connected with statistical inference, data science, machine learning, and AI, alongside industry collaboration programs, support for starting joint studies, and data-science education for high-school students. These activities connect statistical research and ways of thinking with practical challenges and the development of future researchers and specialists.
