sample classes的用法和樣例：
例句
- As for the undivided linear sample space, the kernel function is needed to map onto another high dimension linear space.
對於線性不可分的樣本空間，需要尋找核函數，將線性不可分的樣本集映射到另一個高維線性空間。 - Using different train sample sets, the simulation experiment result demonstrates that the RVM method has more advantages than support vector machine method.
採用不同訓練樣本集的模擬實驗結果表明，相關向量機方法比支持向量機方法具有更多的優點。
