It is a more general version of the linear classifier. ==The classification problem== Statistical classification considers a set of vectors of observations x of an object or event, each of which has a known type ''y''. This set is referred to as the training set. The problem is then to determine for a given new observation vector, what the best class should be. For a quadratic classifier, the correct solution is assumed to be quadratic in the measurements, so ''y'' will be decided based on :$\backslash mathbf\; +\; \backslash mathbf\; +\; c$ In the special case where each observation consists of two measurements, this means that the surfaces separating the classes will be conic sections (''i.e.'' either a line, a circle or ellipse, a parabola or a hyperbola). In this sense we can state that a quadratic model is a generalization of the linear model, and its use is justified by the desire to extend the classifier's ability to represent more complex separating surfaces. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quadratic classifier」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
