size of sample meaning in English
试样尺寸
Examples
- The dimension of sample transfer system is such that the size of sample limited .
样品输送装置要求限定样品的分量。 - The size of sample and weight may be to set more than
样品的大小和重量可能是超过规定了。 - Samples were characterized by tg / dta , x - ray diffraction , tem and measurement of solubility . the particle size of sample is well distributed and the cluster decreases
对样品进行了热重差热， xrd ， tem ，溶解度等测定，证明产物确为mno - One class classification is a machine learning approach different from the traditional pattern recognition approach where two or more class samples are required . however in some real - life cases , we can hardly , even not , get the samples of some classes , or have to pay costly price to obtain the so - needed samples , such as in the case of machinery malfunction . and while in other cases , the sizes of samples among classes are imbalance , such as medical diagnosis
单类分类器是不同于传统模式识别的一种机器学习方法，传统模式识别方法一般需要多个类别的样本(至少两个) ，而在有些场合中，几乎无法获取多类的样本，或者获取其样本所需花费的代价非常高，比如：机器故障中我们不可能为了去获得故障样本而让机器特意产生故障；又有些场合的类别样本个数严重不平衡，比如医学上的疾病特征与非疾病特征的比例是严重不平衡的。 - There is a natural linear order relationship among the data of one - dimensional sample , so which can be ordered according to the size of the sample points , however , since there is no natural linear order relationship among data of multi - dimensional sample , it is impossible to gain multi - dimensional order statistics in accordance with the order of the size of sample , neither is it impossible to extend many useful methods for one - dimensional nonparametric oiatistics to those for high dimensional ones
对于一维样本，由于数据之间存在一种自然的线性序关系，故可按照样本的大小排序，从而得到秩向量。但对于多维样本，数据之间则不存在自然的线性序关系，无法按照样本的大小排序而得到高维样本的次序统计量并由此把一维非参数统计的许多有用的方法直接推广到高维情形，使得对多元数据的统计分析十分麻烦。
