    Multivariate Analyses with Two-Step Dimension Reduction for an Association Study Between <sup>11</sup>C-Pittsburgh Compound B and Magnetic Resonance Imaging in Alzheimer’s Disease by Atsushi Kawaguchi, Fumio Yamashita

    Published 2025-01-01
    “…To study the relationship between Aβ deposition and brain structure, as determined using <sup>11</sup>C-Pittsburgh compound B (PiB) and magnetic resonance imaging (MRI), respectively, we developed a regression model with PiB and MRI data as the predictor and response variables, respectively, and proposed a regression method for studying the association between them based on a supervised sparse multivariate analysis with dimension reduction based on a composite paired basis function. …”

    FAULT DIAGNOSIS BASED ON IMPROVED LOCALITY PRESERVING PROJECTIONS ALOGRITHM by LU Li, CHEN Ying

    Published 2019-01-01
    “…And then use the nonlinear mapping to map the high dimension fault feature into an implicit feature space to dimension reduction. Thus a linear transformation is performed to preserve locality geometric structures of the fault feature,which solves the difficulty of parameter selection in computing affinity matrix,as a result,better fault diagnosis accuracy can achieved. …”
