局部网络

Though numerable models have been put forward, the research on artificial nerve network is still in infancy.

一直以来，由于BP网络存在收敛速度慢，易陷入局部极小点等缺陷，大大限制了它的实用性。

A non-uniformly windowed pyramidical architecture is proposed, the normalizations of the feature vectors of two extraction algorithms are investgated and the Polak-Ribiere learning algorithm is modified to guarantee the weight vector not to converge to non-stable local minima.

文中提出了一种带非均匀窗形式的金字塔状多层神经网络模型I研究了两种特征提取方法的向量规整问题，改进了Polak—Rjbiere学习算法并证明它能够保证连结权向量不收敛到非稳定局部极小点。

This method avoids overfitting, underfitting and local minimum in neural networks.

这种方法避免了在人工神经网络中的过学习、欠学习以及局部最小化的问题。

In the 1990s, a more complete theoretical system - the achievement of statistical learning theory and neural networks, and other than because of the emerging machine learning methods of the difficulties encountered some important, such as how to determine the issue of network structure, overfitting and underfitting, the local minimum points ect, makes the rapid development and improvement of SVM in resolving the small sample, non-linear and high-dimensional pattern recognition problems in the performance of many unique advantages and can function to promote the use of fitted function and other machines learning problems.

上世纪90年代，一个较完善的理论体系--统计学习理论( Statistical Learning Theory，简称SLT)的实现和由于神经网络等较新兴的机器学习方法的研究遇到一些重要的困难，比如如何确定网络结构的问题、过学习与欠学习问题、局部极小点问题等，使得SVM迅速发展和完善，在解决小样本、非线性及高维模式识别问题中表现出许多特有的优势，并能够推广应用到函数拟合等其他机器学习问题中。

In order to enhance the image with better anti-noise ability,this paper proposes a image pre-processing algorithm based on lateral inhibition and adaptive filter,which can not only outstands the image'outline,but also eliminates the noise by adaptively changing the model parameters accordingly to the local image's mean,variance and the noise variance.

为了既能增强图像，又具有较好抗噪性能，提出一种基于侧抑制网络和自适应滤波相结合的图像预处理算法，不仅突出了图像的轮廓，而且能根据图像的局部均值和方差以及噪声方差的不同，自适应地改变模型的参数来消除噪声。

It shows that the network, affected by stream of water, superposes each other leading to the jet of detonator energy cavity and metal fragments which can break the nonel-tube without transmitting detonation yet, so as to make the detonation transmission in some local network break off and bring about misfire.

结果表明，受紊乱水流影响，导爆管网络相互叠加，比较凌乱，致使传爆雷管产生的聚能射流和碎片容易将尚未传爆的导爆管切断或打破，而使局部网路爆轰传递中断，造成拒爆现象的发生。

In the application of NN's to the feedback linearization of nonlinear systems, how to use NN's to approximate the general controller structure is also a problem by many researchers.

现有的解决方法为保证系统的局部和全局稳定性，都要求有一个附加条件。这里提出的解决方法是用神经网络逼近，而不是，从而避免了许多复杂性。

IT NEVER pays to underestimate the bounciness of Asia's emerging economies.

在经历了1997-1998年局部的亚洲金融危机和2001年的网络泡沫之后，旁观者预测亚洲新兴经济体将会经历一个长时间的蛰伏——只有少数几个新兴工业化国家能够快速反弹。

LON is a Local Operating Network put forward by Echelon Corporation in March 1991, and offers a powerful means for distributed control system. Under its support, a new generation of intelligent and low cost field test control product comes into the world.

LON总线是美国Echelon公司于1991年3月推出的局部操作网络，为集散式监控系统提供了强有力的实现手段，在其支持下，诞生了新一代智能化低成本的现场测控产品。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
