剪枝

Firstly the properties of L-MAX frequent itemsets is analysed.Then by extending FP-tree structure an ExFP-tree data structure is presented and the algorithm of ExFP-tree generated is given.According to the character of prefixing paths shared in FP-tree,ExFP-tree implements compressingly storage of transaction information with sharing the transaction information of descendant nodes.

ExFP-tree利用FP-tree共享前缀路径的性质通过共享子孙节点事务信息策略实现大量事务信息的压缩存储；最后基于FP-MAX算法，提出基于ExFP-tree的L-MAX频繁项集挖掘算法，核心思想是先根据L-MAX频繁项集长度约束性质进行前瞻剪枝再进行最大频繁项集挖掘，并通过回溯策略直接定位生成对应事务集。

During the updating and mining of TCIS-Tree several optimal strategies, such as data filtering, heuristically and dynamically adjusting the pruning threshold and mining threshold, and so on, have been explored to make our method efficient.

在TCIS-Tree的更新和挖掘过程中，采用数据过滤、启发式动态调整剪枝阈值、挖掘阈值等若干优化措施，有效地提高算法的时空效率。

GSClu uses bisecting k -means technique and CSClu adopts sub-patterns with gap constraint to cluster the sequence data of corresponding application field.

GSClu和LSClu分别利用带剪枝策略的二分k均值算法和基于有gap约束的强区分度子模式方法对各自领域的序列数据进行聚类。

It is essential that the function never overestimates this number.

这种启发式的算法 h1使用的是基于内存的查表方法，最多允许提前12步做出判断剪枝。

Then, the nodes which don't need to be dealt with are filtrated out, and a STU tree is created. Lastly, the nodes whose information entropy's increase overtops the threshold value are pruned, and the topic information of the Web pages is obtained.

根据配置过滤掉不需处理的相关内容并建立语义模型树，最后对熵增超过阈值的结点进行剪枝并输出抽取的主题信息页面。

When the tree is built, it may be pruned using cross-validation procedure, if need.

当树建好之后，如果需要的话，可能需要用交叉验证来进行剪枝。

Some annuals do not take well to heavy pruning.

你可以给花剪枝，但得视它的情况而定。

Because I h***e no way to sell physical products to foreigners, I can not sell a virtual product, which is fruit of the claimed rights buyer you can pick any of our fruit trees planted, and then has the right to witness the growth of fruit trees and custody, for example, today I Upload sinking, you h***e to buy fruit trees pictures from the photo to see a big physical status of the tree's growth and health status, buyer status by pressing photographs, command watering, fertilizing, pruning and other operations, to enjoy manipulating the entire growth rights and custody and so on, and so on fruit maturity, you also h***e control over the fruits, such as donated to the disaster area or corresponding charitable institutions, etc.

因为我没办法出售实体产品给老外，我能不能出售虚拟产品，也就是果树的认领权（买家你可以任意挑选我们种植的果树，然后拥有对果树成长的见证权和监护权，譬如今天我上传您已经购买的那颗果树图片，从照片上大体能看出此树的成长现状及健康状态，买家按着照片现状，指挥浇水，施肥，剪枝等操作，享受整个成长的操纵权和监护权等，等果实成熟之后，您也拥有果实的支配权，譬如捐赠给灾区或相应的慈善机构等

In LACS, considering the characteristics of classification, we suggest two pruning strategies to confine the generation of concept nodes in the procedure of building concept lattice so that the number of nodes generated decreases greatly.

在LACS系统中，针对分类系统的特点，我们提出两种重要而有效地剪枝策略来限制格构造过程中的节点生成，从而大大减少了所需生成的格节点数目。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
