小缺点

Manchester, armed with its economic review, has a clear sense of direction. But one shortcoming, admitted by Sir Richard Leese, leader of the city council, is its insular approach, regionally and globally. It has an office in Brussels and shares a man in Mumbai, but has no presence in, for example, China or Brazil, nor any landmark trade fair, unlike several big German cities.

经济评论给了曼彻斯特清晰的方向，但是市议会议长理查德·利斯爵士承认说，曼彻斯特孤立向内的发展方式是其缺点，曼彻斯特在布鲁塞尔和孟买有很小的办事处，但是在中国，巴西等地方都没有办事点，也没有重要的商品交易会，这点就做得不如德国一些大城市。

In a brief skit, Leno pushed her to talk about her husband's flaws.

在一个简短的小喜剧节目中，雷诺请她谈谈她丈夫的缺点。

An algorithm based on the square-root unscented Kalman filter is proposed for weight estimation of the neural network, which can overcome the BP algorithm's drawbacks of slow learning speed, high computational complexity and the likeliness to make the study fall into the local minimum points.

提出一种利用平方根无轨迹卡尔曼滤波进行神经网络权值估计的算法，该算法可以克服BP算法存在的学习速率缓慢、计算量大、容易使学习陷入局部极小等缺点以Mackey-Crass混沌时间序列作为神经网络输入，运用SR-UKF算法、UKF算法、BP算法仿真神经网络。

To overcome the disadvantageous of the BP algorithm, slow convergence speed and easy to fall into local small extremum, self-adjustable learning rate and momentum method are used to improve the performance of BP algorithm.

针对BP算法收敛速度慢和容易陷入局部极小值的缺点，利用自适应学习率和附加动量法对基本的BP算法进行了优化，对学习率和动量因子的选择进行了探讨。

But it has the shortcomings of longer calculation and easily getting into local minimum.

但它的计算时间长，易陷入局部极小一直是它不易克服的缺点。

It simulates genetic evolutionary process of organisms and avoids local minimum value.

该方法模拟了生物遗传进化的过程，克服了传统方法容易陷入局部最小值的缺点。

After a while, his myth becomes a little much—he actually was born in a log cabin with a dirt floor—so much that we begin looking for flaws, and they're there: the bad marriage, some maladroit comments on racial inferiority.

之后不久，他的神话就有点多了（实际上他出生在一个带有泥土地面的小木屋里）以至于我们开始希望能找到些缺点，这儿就是：一桩不美满的婚姻，某些关于种族卑下的笨拙的评论。

The experiment results prove that the way with regularization technology is better than the way without regularization technology. In order to overcome the limitation of the regularization method, chapter 6 builds an irregular MRF model suitable for the motion estimation of feature point based on MAP-MRF frame. The energy function, which can reflect the joint probability distribution of motion parameters and the constraints relation of local 3D motion parameters, is established in irregular MRF.

为了解决正则化方法只能分析非刚体局部三维运动的缺点，第6章在基于MAP-MRF的分析框架中建立了与特征点运动估计相对应的非规则MRF模型，构造了非规则MRF模型中反映非刚体局部三维运动参数之间约束关系和运动参数联合概率分布的能量函数，通过能量函数最小化估计运动参数。

However, a main drawback of this method is the existence of local minima when generating a path for a robot to follow.

但是这种方法的缺点是在路径规划的过程中，机器人经常会陷入局部极小。

Aiming at the drawbacks of traditional BP neural network, such as converging slowly and tending to get into the local minimizer, the particle swarm algorithm is introduced into the training of neural networks.

此外针对传统的BP神经网络存在收敛速度慢以及容易陷入局部极小值的缺点，引入粒子群算法对神经网络的学习训练进行优化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
