Image Processing Center, School of Astronautics, Beihang University, Beijing 100191 Image Processing Center, School of Astronautics, Beihang University论文摘要: Using hyperspectral images to detect targets, the classical detection algorithms mainly focus on the second-order statistics. For example, the popular Constrained Energy Minimization algorithm uses the data's correlation matrix to detect targets.

论文摘要：利用高光谱图像进行目标检测，传统的目标检测算法主要使用二阶统计量，例如国际上流行的约束能量最小化(Constrained Energy Minimization，CEM)算法使用数据的二阶相关矩阵来进行目标检测。

The relationship between the topology and convegence of networks is approached and the reason causing overtraining and overfitting is analysed. Then the redundant weights and nodes in the network are defined by using improved activity function and a new algorithm called the BPNSO for determining the network structure for any application is proposed, which use dual optimization objective function combining the mean squre error of the network output with network complexity penalty function.

文章对网络拓扑结构与网络收敛性和稳定性的关系进行了探讨，分析了网络出现Overtraining或Overfitting的原因和解决的目标，提出了神经网络结构优化的策略，改进了活化函数，定义了冗余权值和冗余节点的概念，为辨识和删除冗余权值和冗余节点，提出采用优化目标函数中增加网络复杂度罚函数的双重优化目标函数，并对罚因子提出了基于学习误差和权值的自适应动态调整公式，论文定义了这种BP网络结构优化方法为BPNSO，并给出了完整的计算流程。

It is proved that strictly efficient point set of the objective space is connected when objective function is cone convex－like,and that if objective function is cone convex set－valued mapping,then strictly efficient solution set is also connected.

证明了当目标函数为锥类凸的集值映射时，其目标空间里的严有效点集是连通的；若目标函数为锥凸的集值映射时，其严有效解集也是连通的。

A knowledge-based correction term in the objective function is proposed. The relationship between state estimatin and parameter estimation is analyzed. A strategy of projecting the objective function from the augmented solution space to the parameter space is proposed and proved.

该文提出基于经验知识的参数估计目标函数修正项，导出状态估计与参数估计目标函数极值的关系，由此提出将目标函数从增广解空间垂直投影到参数空间的估计策略，并指出参数估计偏差的成因。

描述了Contrast box算法和搜索有用目标段处理过程，分析了阈值权值系数和目标所占像元面积选取的不同对图像有用目标段搜索的影响，给出了每幅图像的统计信号量。

Certain control words, referred to as destinations, mark the beginning of a collection of related text that could appear at another position, or destination, within the document.

对于某个控制字，作为目标提及，标记一段有关系的文本的起点。。。（再议：此句汗，如果作为考研翻译亦不为过，destination当什么讲？目标，目的地，目标单元格？

Object linking is useful if you want the destination file to always contain the most up-to-date information, for if the source file changes, the object in the destination file is updated automatically.

句意：如果你想要目标文件一直拥有最新的信息，目标链接就很有用，因为利用此功能，如果源文件改变，那么目标文件自动作相应的更新。
