查询词典 vector bundle

The method is realized via the following steps: first to apply Isomap or LLE to get the embeddings of the original data set in the low dimensional space; then to obtain support vectors, which are the most significant and intrinsic data for the final classification result, by using support vector machine on these low dimensional embedding data; subsequently to get support vectors in the original high dimensional space based on the corresponding labels of the obtained low dimensional support vectors; finally to apply support vector machine again on these high dimensional support vectors to gain the final classification discriminant function.

数据挖掘是数据库知识发现中最重要的步骤之一，其目标是从获取的数据中高效准确地挖掘出我们所需要的信息。在实际应用中，数据往往呈现海量、高维、非线性等特性，这些特性给数据挖掘带来了很多问题，例如海量特性导致的计算效率低下问题、高维特性带来的维数灾难问题和非线性特性引起的线性模型失效问题等。幸运的是，实际中高维数据的属性之间往往存在一定的规律性和相关性，即实际数据经常存在着外在与内在两个维数。

Finally, the constructed β3AR gene antisense expression vector was identified though restriction endonuclease analysis and sequencing. RESULTS: Target gene of about 1.2 kb was successfully cloned into retroviral vector pLNCX. The sequence of cloned β3AR fulllength cDNA was identical to the reported one in GenBank.

Although we can preallocate a given number of elements in a vector, it is usually more efficient to define an empty vector and add elements to it (as we'll learn how to do shortly).

虽然可以对给定元素个数的 vector 对象预先分配内存，但更有效的方法是先初始化一个空 vector 对象，然后再动态地增加元素（我们随后将学习如何进行这样的操作）。

AIM: To construct the eukaryotic expressing vector of human cbl and test its expression in African green monkey kidney cell line COS 7.
