    Non-linear modeling of 1H NMR metabonomic data using kernel-based orthogonal projections to latent structures optimized by simulated annealing. by Fonville, J, Bylesjö, M, Coen, M, Nicholson, J, Holmes, E, Lindon, J, Rantalainen, M

    Published 2011
    “…Simulated annealing (SA) was used for effective and automated optimization of the kernel-function parameter in K-OPLS (SA-K-OPLS). Our results reveal that the non-linear K-OPLS model provides improved prediction performance in three separate metabonomic data sets compared to the linear OPLS model. …”

    Discrimination of white ginseng origins using multivariate statistical analysis of data sets by Hyuk-Hwan Song, Ji Young Moon, Hyung Won Ryu, Bong-Soo Noh, Jeong-Han Kim, Hyeong-Kyu Lee, Sei-Ryang Oh

    Published 2014-07-01
    “…Results: The origins of white ginsengs in two test sets (1.0 μL and 0.2 μL injections) could be successfully discriminated by the OPLS-DA analysis. From OPLS-DA S-plots, KWG exhibited tentative markers derived from ginsenoside Rf and notoginsenoside R3 isomer, whereas CWG exhibited tentative markers derived from ginsenoside Ro and chikusetsusaponin Iva. …”
