Ranked Modeling of Liver Diseases Sequence
Leon Bobrowski, Tomasz Łukaszuk, Hanna Wasyluk · European Journal for Biomedical Informatics · 2007
Ranked model in the form of linear transformation of multivariate feature vectors on a line can reflect a causal order between liver diseases. A priori medical knowledge about order between liver diseases and clinical data sets has been used in the definition of the convex and piecewise linear (CPL) criterion function.The linear ranked transformations have been designed here through minimization of such CPL criterion functions.
