查询词典 vacuous subset

In this method, all stable sub-intervals in the training sequence were located for each pixel as possible background. Then a classify data set was constructed by the median values of each subinterval. A background subset was obtained from the data set by unsupervised clustering. Accordingly the initialized background was obtained from the background subset.

首先利用滑动可变窗口检测每个像素的所有不重叠平滑子序列，获取可能背景；然后选择每个平滑子序列的中值样本点构建分类序列集，根据未知类别的无监督聚类识别思想获取背景子集，实现背景初始化。

Genius is a subset of human nature, just as neurotics are a subset of human nature.

Inspired by these results, in this paper, we first give the definition of a new mapping ? uniformly Lipschitz asymptotically nonexpansive mapping on a compact subset of a uniform convex Banach space, then construct three-step iterative sequences of uniformly Lipschitz asymptotically nonexpansive mapping in this subset . We proved the convergence of this three-step iterative sequences for uniformly Lipschitz asymptoticallynonexpansive mapping, Further more, we proved this three-step iterative sequences with an error member converge to fixed points.

从中得到启发，在本文我们首先定义了一致凸Banach空间某非空紧子集上的一种新的映射——一致李普希兹渐进非扩张映射，在该紧子集上构造关于一致李普希兹渐进非扩张映射的三步迭代序列以及具误差的三步迭代序列，先来讨论三步迭代序列的收敛性，进而讨论具误差的三步迭代序列的收敛性。

From the analysis, we can conclude that at least three aspects will cause cross-cultural pragmatic failure: a. The intersection of pragmeme subset A and pragmeme subset B is an empty set; b. Interlocutor A's pattern of pract elements coupling is different from that of interlocutor B's; c. The outranging of allopract causes the transferring from a pragmeme to another pragmeme. The three aspects of pragmeme theory enrich the studies on cross-cultural pragmatic failure.

通过分析，我们得出跨文化语用失误的原因有三：第一，交际者双方对于某一语用行为的语用位交集为空集时会导致跨文化语用失误；第二，交际者双方选择的语用素集合中元素之间耦合方式不相同时会导致跨文化语用失误；第三，交际者一方的语用变体超出对方语用位范畴时会导致跨文化语用失误。

The IKONOS data of Beijing Yuanmingyuan is fused with Tasseled Cap and PCA methods.The fusion results are analyzed and compared with full image and vegetation subset.The result shows that,in study area,the KT fusion method is better than PCA in full image and vegetation subset.The fusion results are differential with different KT transformation matrix,and the method of fusion should be chosen according to study area,data,and classification methods.

应用缨帽变换和主成分分析方法，对北京圆明园周围的IKONOS全色波段和多光谱波段进行融合，并分别对整景影像和植被区的融合结果进行对比研究，结果表明：在该实验区，整景影像和植被区缨帽变换融合结果都优于主成分析结果，不同的缨帽变换系数矩阵在整景影像和植被区融合质量会有差别，应根据具体地点、时相，分类方法做适当的选择。

Orthogonal subset is extracted from orthogonal geometry by collecting all traces that have a shot line and a receiver line in common, therefore the two lines are vertical bisectors. An orthogonal subset is single-fold coverage of a 3-D dataset.

在正交子集中，各种规则干扰，如面波、声波、折射以及由地面不均匀体产生的散射，在三维空间上，形成以震源或散射点为顶点的锥形体，线性噪音为从圆锥顶点辐射出的直线，具有恒定的视速度。

In addition, this subset can also facilitate global electronic communications in Chinese by providing a shared subset of ideographs.

再者，藉著提供一个国际表意文字子集，国际间的中文电子通讯便能得以改善。

The algorithm firstly uses some robust techniques to construct an inliers set of matching points. Then it takes the epipolar distance as the optimal criterion and search optimal subset in the inliers set under the greedy strategy. Finally, the fundamental matrix is calculated with the optimal subset.

利用各种鲁棒技术获得内点集，以点到极线的距离作为最优量度标准，采用贪心策略在内点集中寻找最优子集，并利用最优子集来计算基本矩阵。

Each subset has only one kind of MOA. Then local QSTR models were constructed for each subset and global QSTR model was built for the whole training set with several MOAs.

对于毒作用机理未知而毒作用方式已知的毒性数据集，先将化合物按照毒作用方式归为不同子集，然后对每个子集建立局部QSTR模型，并对包含多种毒作用方式的整体数据集建立全局模型。

And etc but also overcomes the shortcomings of the true-false subset semantics and twin-subset semantics.

而且克服了前期工作真假子集语义和双子集语义表示的缺陷。
