A Hyper-plane method is efficient in computing but hard to fit nonlinear situation; on the contrary, a Hyper-sphere method has better fitness for nonlinearity but hard to compute. This project proposes an innovative method, called Hyper-Cube Method (HCM), to classify objects effectively under nonlinear environment. Given a set of objects with some classes, HCM separates the objects into different cubes, where each cube is assigned to a class. Via the union of these cubes, we utilize mixed integer programs to induce classification rules with better rates of accuracy, support and compactness. Various practical data sets including benchmark biological and medicine data sets, financial data set of Taiwan electronic companies (2002~ 2011), and a data set of world competitiveness of IMD (2002-2010) are tested to illustrate the advantages of HCM over current methods such as Decision tree methods, hyper-plan methods, and Hyper-sphere methods. This research project will last for two years. The first year is put on reviewing current methods about classification then to develop theoretical propositions of optimal methods. The second year is to design an effective Hyper-Cube algorithm and classify large scale multiple scaling data using HCM to compare its effectiveness with current classification methods. 官方說明文件#: NSC101-2221-E009-062-MY2 URI: http://hdl.handle.net/11536/98872https://www.grb.gov.tw/search/planDetail?id=2648653&docId=399974 顯示於類別： 研究計畫
