1) between cluster variation
类间差异
2) interclass difference matrix
类间差异矩阵
1.
The interclass difference matrix is calculated by using the fault class feature data from simulation in order to determinate the ambiguity sets.
算法利用电路仿真故障特征数据计算故障的类间差异矩阵,从而完成故障类模糊集的确定。
3) within cluster variation
类内差异
4) uneven class sizes
类别差异
1.
Since proximal support vector machine(PSVM) is susceptible to uneven class sizes and is sensitive to outliers and noises in the training set,a robust PSVM was proposed.
标准近似支持向量机受类别差异影响和噪声、野值数据干扰较重,使得分类能力不高。
2.
When training sets with uneven class sizes are used,the classification error based on C-Support Vector Machine is undesirably biased towards the class with fewer samples in the training set.
针对这两种问题,分析了产生的原因,提出了一种加权支持向量机算法,补偿了类别差异造成的不利影响,加快了重复样本的决策速度。
3.
When training sets with uneven class sizes were used,the classification error based on traditional hyper-sphere support vector machine was undesirably biased towards the class with fewer samples in the training set.
该算法综合文档内容信息和超链接信息作为文档特征向量,针对传统超球支持向量机算法在不同类别样本数目不均衡时训练分类错误倾向于样本数目小的类别的问题,利用加权因子补偿了类别差异对算法推广性能造成的不利影响。
5) product difference
品类差异
1.
The customer perceived value is the main driving factor for the formation of brand loyalty which is affected by gender difference and product difference directly.
消费者的品牌感知价值存在性别差异和品类差异,这种差异直接影响消费者品牌忠诚的形成。
