data n. 1.资料,材料〔此词系 datum 的复数。但 datum 罕用,一般即以 data 作为集合词,在口语中往往用单数动词;如系指一件资料,则说作 this data〕。 2.〔美国〕(观察所得的)事实,知识。 a data book 参考资料书。 gather data on ...收集…的资料[数据]。 The data is not enough to be convincing. 资料不足,尚难令人信服。
In the helicopter example , the eight flight times become the raw data vector 在纸飞机的实例中, 8次飞行的时间成为原数据矢量。
The net does a quite respectable job , in our opinion , of recognizing code - we would love to hear how it does on your data vectors 就我们的观点而言,网络完成了一项值得尊敬的工作,来识别代码我们将会乐意倾听,对于您的数字向量它是如何做的。
This method constructs covariance matrix by utilizing data vectors in different range lines and projects phase error vector into noise sub - space which is formed by eigendecomposing the covariance matrix 该方法利用不同距离单元的观测矢量构造协方差矩阵,然后通过对协方差矩阵特征分解得到噪声子空间,最后将相位误差矢量向噪声子空间投影来估计多普勒调频率。
Clustering analysis is one of most heated research topic of the day . data clustering , a unsupervised classifying method , is the process of grouping together similar multi - dimensional data vectors into a number of clusters or bins 聚类就是把一个没有类别标记的样本集按某种准则划分成若干类,使类内样本的相似性尽可能大,而类间样本相似性尽量小,是一种无监督的分类方法。
Abstract : a blind multiuser detection algorithm based on nonlinear least squares method is proposed . it is proved that as the number of the sampled data vectors is large , the performance of this algorithm tends to the performance of moe . simulations indicate that the performance of this algorithm is better than that of cmoe , and can be used in variable enviorment 文摘:基于非线性最小二乘方法,提出了一种新的多用户检测算法,并且证明了在大样本取值的情况下,这一算法的性能逼近于moe算法的性能.仿真分析表明,算法性能优于cmoe算法,且能适应环境的变化
