sample classes的用法和样例：
例句
- As for the undivided linear sample space, the kernel function is needed to map onto another high dimension linear space.
对于线性不可分的样本空间，需要寻找核函数，将线性不可分的样本集映射到另一个高维线性空间。 - Using different train sample sets, the simulation experiment result demonstrates that the RVM method has more advantages than support vector machine method.
采用不同训练样本集的仿真实验结果表明，相关向量机方法比支持向量机方法具有更多的优点。
