针对远海任务舰船备件器材的分类管理,通过运用支持向量机理论,充分发挥多尺度核在非线性分类中的优势,借助最小二乘原理,构建了多尺度最小二乘支持向量机学习模型。在实际运用中,通过选用高斯径向函数作为多尺度核函数,以训练样本数据分布的离散系数作为核函数宽度参数取值依据,采取ECOC方法建立了多类分类模型,实例计算表明,该方法对远海任务舰船备件器材的分类是有效、可行的。
針對遠海任務艦船備件器材的分類管理,通過運用支持嚮量機理論,充分髮揮多呎度覈在非線性分類中的優勢,藉助最小二乘原理,構建瞭多呎度最小二乘支持嚮量機學習模型。在實際運用中,通過選用高斯徑嚮函數作為多呎度覈函數,以訓練樣本數據分佈的離散繫數作為覈函數寬度參數取值依據,採取ECOC方法建立瞭多類分類模型,實例計算錶明,該方法對遠海任務艦船備件器材的分類是有效、可行的。

In view of the classification management problems of pelagic task ship spare parts equipment, based on the support vector machines theory, making full use of the advantages of the multi-scale kernel in nonlinear classification, with the aid of the least squares principle, this paper establishes a multi-scale model of least squares support vector machine. In practical application, by selecting Gauss radical function as the multi-scale kernel function, taking the discrete coefficient of the training samples data distribution as the width parameter value reference of kernel function, the multiclass classification model is established by ECOC method. The result indi-cates that this method is effective and feasible for the classification of pelagic task ship spare parts equipment.
