The core of this patent lies in constructing a data element management method based on a three-dimensional tree structure. Compared to traditional two-dimensional data management, this structure ...

Decision trees often give simple descriptions of complex, nonlinear relationships between several predictors and a univariate or multivariate response. But if the response is a high-dimensional vector ...

The thrust of tree techniques is the extraction of meaningful subgroups characterized by common covariate values and homogeneous outcome. For longitudinal data, this homogeneity can pertain to the ...
