样本比例 meaning in Chinese

sample proportion

Additionally , the optimum structure and parameters of the support vector machine can easily be determined by the learning process , however the neural networks can not . an information gain of signature signals is introduced to assess the contribution of the signature signals to diagnosing faults in rotating machines
同时发现，存在一个最佳训练样本比例值，在该比例值上，不同核函数支持向量机的故障诊断错误率均趋于稳定，也就是说这个比例值确定了在保证故障诊断准确率的条件下，所需要的最少训练样本数。
