background: diabetes mellitus is a metabolic disorder and its subsequent complications such as retinopathy, nephropathy, ulcers,disability, and amputation increase the burden of the disease. patient knowledge-improving programs are employed to prevent disease progression and to improve the quality of life of the patients. in this way, we need to characterize the groups of patients in urgent nee...

A nonparametric function estimation method called SUPPORT (“Smoothed and Unsmoothed Piecewise-Polynomial Regression Trees”) is described. The estimate is typically made up of several pieces, each piece being obtained by fitting a polynomial regression to the observations in a subregion of the data space. Partitioning is carried out recursively as in a tree-structured method. If the estimate is ...

Piecewise regression represents a powerful tool to derive accurate yet modular models describing complex phenomena or physical systems. This paper presents an approach for learning PieceWise NonLinear (PWNL) functions in both supervised and semi-supervised setting. We further equip the proposed technique with method automatic generation of additional unsupervised data, which are leveraged impro...
