In order to overcome the problems of slow rate of convergence and falling easily into local minimum in BP algorithm, a new improved homotopy BP algorithm is put forward. It transfers the identity matrix of output mode in common use into the binary system.

为克服标准BP算法中存在的网络学习收敛速度慢、容易陷入局部极小等问题，引入同伦算法，提出了一种将同伦论与快速BP算法结合的改进算法，并采用二进制结构表示输出模式矩阵。

The data symbols may be sent on orthogonal spatial channels with the eigenmode matrix, on different spatial channels with the steering matrix, or from different transmit antennas with the identity matrix.

数据符号可以用本征矩阵在正交空间信道上进行发射，用导引矩阵在不同的空间信道上进行发射，或用单位矩阵从不同的发射天线进行发射。

Since an elementary reflection in the form of a Householder matrix can reduce any orthogonal matrix to this constrained form, a series of such reflections can bring any orthogonal matrix to the identity; thus an orthogonal group is a

因为 Householder 正交矩阵形式的基本反射可把任何正交矩阵简约成这种约束形式，一系列的这种反射可以把任何正交矩阵变回单位矩阵；因此正交群是

Based on a brief review on developments of number system, a new developed pattern is proposed. The quaternion is extended to a matrix form aI+bA+cB+dC, in which the identity matrix I and three special matrices A, B, C correspond to number 1 and three units of imaginary number i, j, k, respectively.

在数系发展的基础上，提出了一种新的发展模式：四元数推广为矩阵形式aI+bA+cB+dC，其中单位矩阵I和3个特殊矩阵A，B，C分别相应于数1和虚数单位i，j，k。

Any square matrix (a matrix is square if its number of rows equals its number of columns) is an identity matrix if all values are 0 except those diagonal from the top left to the bottom right which instead have the value of 1 - the locations where the row position equals the column position.

任何方形矩阵(一个矩阵的行，列数相同)，只要是从左上角到右下角这条对角线上的元素值为1，其余为0的，就是一个单位矩阵。

A code C can be constructed from a Paley matrix of order n,where n is a power of odd prime. The code contains codewords 0 =(0,0,......,0),1 =(1, 1,....., 1) and the rows of/2 and (-5 /-- J)/2, where I and J are respectively identity matrix and the matrix with all entries equal to one.

从凡阶＊缸矩阵S出发，可以构造一个码氏它含有码字0＝叮0；…；0X1二O；1，…；1）以及矩阵（S＋I＋刀／2和（一S＋I＋刀／2的全部行向量，其中凡是奇素数的方幂；了和J分别是单位矩阵和全1矩阵。

To detect more targets, the whitened data Z are projected onto the orthogonal subspace of w using the orthogonal subspace projector P⊥= W I .W.1WT, to eliminate the detected target, where I is an L×L identity matrix and W =.

为了要发现较多的目标，被数据白的 Z 被在 w 的直角次空间之上使用直角的次空间投光器 P 第一⊥= W 计画。W。，除去那发现了我是 L × L 身份点阵式和 W=的目标。

The CDMA type signals may also be processed using a pre-coder incorporating a Discrete Fourier Transformer matrix or Identity matrix to reduce the Peak-to-Average Power Ratio across the OFDMA system.

也可以利用并入离散傅立叶变换器矩阵或单位矩阵的预编码器来处理CDMA型信号，以降低OFDMA系统中的峰均功率比。

When the actuated joint was rotary actuation, kinematic Jacobian matrix of the manipulator was a diagonal matrix. So it was an uncoupled mechanism. As the actuated joint was linear one, Jacobian matrix of the manipulator was an identity 3×3 matrix and its determinant was equal to one. Manipulator, therefore, was singularity-free fully-isotropic throughout the entire workspace.

当以转动输入为主驱动时，运动雅可比矩阵为3×3阶对角阵，故机构为无耦合并联机构；当以移动为主驱动时，雅可比矩阵为3×3阶单位阵，且其行列式的值为1，所以在整个工作空间内机构表现为无奇异完全各向同性。

直至目前为止，世界和时代华纳已经发布了几个电影在HD格式，包括箭鱼，最后的武士，百万美元宝贝，歌声魅影，阿波罗13号，盗亦有道，末日与安宁，与即将发布要伯尔的身份，矩阵，肖申克的救赎，充分金属外套，锅盖头和方志的迪克。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
