The research team of Professor Kyoungjae Lee of the Department of Statistics at Sungkyunkwan University, through joint research with Professor Won Chang of Seoul National University and Professor Xuan Cao of the University of Cincinnati, developed Bayesian inference for the hidden dependence structures of multi-group high-dimensional data. A Dependence Map in High-Dimensional Data In today’s scientific and industrial fields, high-dimensional data in which numerous variables are observed simultaneously, such as genomic, climate, financial, and sensor data, are rapidly increasing. In such data, an important problem is to learn the dependent structures connecting the variables and to identify a “dependence map” that reveals hidden information in massive datasets. For example, in climate data, temperatures in nearby regions may be related to one another, and in genomic data, genes located in adjacent positions may act together. If such dependence can be incorporated into inference, more efficient inference is possible than analyzing each variable separately.
