查询词典 at the distance

Isomap is one of the representative techniques of nonlinear dimensionality reduction.It extends classical multidimensional scaling by considering approximate geodesic distance. However,Isomap is sensitive to noise because the approximate geodesic distance is constructed on the basis of Euclidean distance. In this paper,a kernel-induced distance metric defined in the feature space is introduced instead of the Euclidean distance to evaluate the geodesic distance and construct the corresponding neighborhood graph.

采用核方法在特征空间推导出一类异于欧氏距离的新度量，代替等度规特征映射中的对噪声敏感的欧式距离，用新度量构造测地距离和相应的最小近邻图，提高Isomap算法的抗噪声能力。

Apparently, the results is determined extremely by theoretical algorithm. In 147 zinc-finger-containing genes, 50nt identity sequences were extracted. The results hint that 15 genes may related to block evolution. we analyzed the phylogenetic map of these 15 genes by uncorrected distance, Jukes Cantor distance, Tamura distance, Tajima-Nei distance, Jin-Nei distance or Kimura distance correction, but we found no satisfied result according to the block exchange pattern mentioned before. Introducing Bootstrap test to assistant correction, an comparatively perfect map was drown by Neighbor Joining method.

以147个含锌指基因为模板，我们搜索了其中的50nt一致序列作为板块式进化的核心，获得15个相关基因，应用无校正距离、Jukes Cantor校正距离、Tamura校正距离、Tajima-Nei校正距离、Jin-Nei校正距离和Kimura校正距离等分析了他们之间的进化关系，结果与已知的板块交换模式吻合度较差，引入靴带检验对Jukes Cantor校正距离结果进行统计学校正，并重新用Neighbor Joining方法绘制进化图，结果可靠性大大提高。

However, after I came to understand distance education more deeply, I find that network distance continuation education has many advantages. Firstly, it breaks through the limitation of time and distance. It enables the students all over the country to get instructed from those top level teachers, take the most advanced teaching method, and enjoy richer education information resource. Secondly, it profits in extending the teaching scope, providing more education chances and more flexible way of learning, which make it possible to let more people accept education. Thirdly, the modern network distance continuation, which is based on information, offers a good space-time platform for a lifelong learning. At last, the modern network distance continuation makes students to focus on self study, which help them to fully develop their proactivity, intuitivity and creativity. For the four reasons mentioned above, finally, I chose network distance continuation education as the way of my further education.

但是，经过深入了解之后，发现远程网络继续教育是有很多的优势的，第一，它可以突破时空的限制，使全国各地的学生都能接受一流水平教师的教导，接受最先进的教学方法，享有更丰富的教学信息资源；第二，有利于扩大教学规模，提供更多的学习机会和更灵活的学习方式，使更多的人可以接受教育；第三，以基于信息技术的现代远程网络继续教育，为终生学习的实现提供了时空平台，为人们提供更多开展的实施终身学习的机会；第四，现代远程网络继续教育以学习者自学为主，充分发挥学习者自主学习的主动性、积极性及创造性，综合以上四点，我最终选择远程网络继续教育作为我继续学习的途径。

During open/close movement, the distance of condylar movement is smaller than normal occlusion(P.05). During protrusion/retrusion movement, protrusion extent increase,the distance of condylar movement is bigger than normal occlusion(P.05). During lateral excursion, the trace in sagittal plane of the non-working side condyle is more incline than protrusion movement trace and the distance of the left non-working side condylar movement is larger than the right. During mediotrusion/right movement, the left biggest space distance is larger than normal occlusion and the transversal condylar inclination is smallar than normal occlusion when the distance of condylar movement is 5mm, the difference is statistically significant.

在整个学习过程期间，教师和学生处于准永久性分离状态（以此与常规面授教育相区别）；教育组织在材料计划、准备和学生支持服务准备两方面的影响（以此与个别学习和自教计划相区别）；技术媒体（印刷媒体、视听媒体或计算机媒体）作为课程内容的载体，把教师与学生联系起来；提供双向通信，使学生可以主动对话并从对话中受益（以此与教育技术的其他应用相区别

First,the distance ratio between within-class and between-class of each column of mixing matrix is computed by using a distance measurement.Then,for each class,the mixing matrix and independent components are re aligned by sort ascending according to the distance rate,and the columns of the weight matrix with smaller distance ratio and the corresponding features are reserved.Finally,the best feature set is selected by genetic algorithm from these foregoing feature vectors.
