摘要
结合纺织品悬垂性能参数的特点,在原有径向基核函数基础上,应用SVM-Mercer核进行新的核函数构造,建立了基于SVM-Mercer的织物悬垂性评估模型.文中对该模型的评估结果进行比较,并分析回归精度ε对评估结果的影响.结果表明:基于SVM-Mercer的织物悬垂性能评估模型可行,其评估精度有了一定程度的提高;ε的选取对评估结果有重要影响,在训练过程中宜首先确定.
A new assessment model based on SVM-mercer is constructed by integrated the feature of fabrics drape data and the theory of Radial Basis Function （RBF） kernel. The assessment results on the model are compared with the one of reference [1] and the effect of regression accuracy ε on assessment is analyzed. The experimental resuits indicate that the assessment precision is increased and the assessment model is feasible. Meanwhile regression accuracy ε, determined firstly in the training, is important to the result of assessment.
