This new strategy gets the potential support vectors and removes the non-boundary outlier data immixed in the other class by using fuzzy clustering. That can greatly reduce the scale of the training sample set and improve the generalization performance by effectively avoiding over-learning caused by outlier data, and finally speed up learning rate without reducing the classification accuracy.

该策略运用模糊聚类方法快速的提取出潜在支持向量并去除类内非边界孤立点，在减小训练样本集规模的同时，能够有效地避免孤立点数据所造成的过学习现象，提高了SVM的泛化性能，在保证不降低分类精度的前提下提高训练速度。

The shortages of typical BP algorithm are that its convergence speed is slow and it possibly mires to local minimum. To solve the former shortage, BP algorithm was modified from several aspects, such as adjusting learning rate adaptively, adding momentum factor, preprocessing training data and modifying network structure, etc.. For the latter shortage, factor γ was introduced to avoid most of local minimum and accelerate the convergence speed.

为解决现有BP算法收敛速度慢的问题，对BP算法进行了改进，采用了动态改变步长、加入动量因子、对训练样本进行预处理以及调整网络结构等措施；针对经典BP算法可能收敛到局部极小点的问题，加入γ因子，可以避免大部分的局部极小值，从而使网络的收敛速度加快。

At the same time, chaotic pseudo-random sequences generator based on nonlinear dynamic filter security model are constructed to select the frequency hopping points for NDFT, improving the overall system security. 3、Aiming at replay attack of networks in the remote speaker recognition systems and distributed databases speaker recognition systems, a time-stamp watermarking method is brought, which quantizes magnitude coefficients of NDFT. The time-stamp watermarking is embedded into the user's voice sample/voice characteristic information to resist on the replay attack.

Experiments showed that the data points art inure separable in this algorithm. The algorithm can overcome tilt' faults of traditional Cell-Based algorithm, which need to he recomputed from the scratch for even' change of the parameters. It also tins higher detection rate at higher convergence speed.

试验结果表明，该算法能有效突出样本之间的差异，克服传统基于距离的孤立点发现算法易随参数变化而需调整单元结构的缺点，且具有更准确的检测率和较快的收敛速度。

Because there are the characteristics of uncertainty and mixing meta-pixels in the remote-sensing images, the classical fuzzy c-means method has a low accuracy in the remote-sensing image clustering. This paper improves the fuzzy c-means method. And it adds a-priori information into the patterns to change the method as a semi-supervised clustering. In the clustering process, the unlabelled patterns compare similarities with the labeled patterns, and then the accuracy of the algorithm can be increased.(3)The paper proposes an interactive learning-based image mining in remote sensing.

由于遥感图像各类别在特征空间中散点图的分布的特点，本文对传统的FCM聚类算法进行改进，并且加入先验信息之后，将原来的非监督的聚类变成一种半监督的聚类方法，通过与已标签的样本进行相似性比较，能有效地提高聚类算法的准确度。

It can identify the denomination and paper currency and seek out deformity. Concerning shortages of the previsions design of Paper Currency Identification Instrument, such as poor seeking-out deformity and defective unity of paper currency between new version and old one, a new identifying method is promoted in the thesis that Eight-line Seeking-points Method based on regional gray scale and paper currency sample database is on service by means of the points from paper-scanned background edge looking for the points on the paper edge.

本文针对当前国内图像识别技术在纸币清分机中的应用不成熟而导致对人民币挑残能力弱、在人民币新旧程度和面向分类中的一致性差的情况，提出了一种基于区域灰度特征提取的八线找点算法和区间估计建立标准样本库相结合的图像识别方法。

In the pre-experiment stage, we analyze the colors and shapes of 135 visual illusions by Kitaoka, a Japanese scholar. The result is referenced in the formal experiment. Formal experiment includes three sub-experiments: Experiment 1 is to discuss the effect of the displacement of disjunctive center on visual illusions' movement; Experiment 2 is to discuss the effect of image layout on visual illusions' movement; Experiment 3 is to discuss the effect of color configuration on visual illusions' movement. Post-experiment stage is a repeat of formal experiment to confirm the results.

前测实验是进行日本学者北冈明佳的135幅错视动态作品之造形与色彩的分析，并将分析结果作为正式实验样本之参考；正式实验分成三个实验进行探讨，实验一在探讨分割点中心的位移对於错视图形在视觉动态上的影响，实验二在探讨图形配置对於错视图形在视觉动态上的影响，实验三在探讨色彩配置对於错视图形在视觉动态上的影响；而后测实验则是将正式实验之实验结果进行再实验，以印证正式实验之结果。

本文对大连夏季室外凉亭下的环境特征和人的热舒适性做了主观问卷调查研究，通过对428个有效样本的研究与分析，回归得到了人体热舒适投票值TCV与人体平均温度和周围空气温度之间的关系式，在满足该式的条件下，人体平均温度在35.7~36.5℃之间，空气温度在25.5~30.4℃之间变化，且空气相对湿度保持在40%~60%，风速在0~1.5m/s之间波动，人体都可以达到热舒适状态，并发现人们在室外自然环境下往往感觉吹风不足，这点正好与传统空调中人们易产生吹风感的抱怨相反，从而为适当提高送风速度与温度，节约空调能耗奠定了基础。
