Significance-based Support Vector Machines for Incomplete Data

KiYoung Lee  Kwang H.Lee  Doheon Lee  
【摘要】:正 Conventional support vector machines (SVMs) find optimal hyperplanes that have maximal margins by treating all data equivalently. In the real world, however, the data within a data set may differ in degree of uncertainty or significance due to noise, inaccuracies or missing values in the data. Hence, if all data are treated as equivalent, without considering such differences, the optimal hyperplanes identified are likely to be less optimal. In this paper, to more accurately identify the optimal hyperplane in a given uncertain data set, we propose a significance-based distance from a hyperplane using significance degrees, and formulate three kinds of significance-based SVMs.
