剪枝

If the data of a path can not been found in the abstractor definition, then it is not generalized and is pruned. The basic principal of hierarchy tree has two steps.

若某路径上对应的数据不能在概念层次树上找到更为抽象的定义，无法对该数据进行概化操作，则认为其是与挖掘任务关系不大的，执行剪枝操作。

Then we found Ambrosio. He showed up on time and took his work seriously,' pulling weeds, cutting fallen branches and spreading mulch.

后来我们找到了安布罗休，他每次都准时到，干活很认真，拔草、剪枝、撒肥料。

The duct is diffusingly narrow. The bile duct wall is stiff without flexibility, taking the shape of leaden tube. The normal intrahepatic bile duct is deprived of its "willow"-style softness and smoothness. The intrahepatic bile duct branches are to scarce to reach the edge of the liver, taking the shape of "withered arborization" or "pruned trees".

胆管呈弥漫性狭窄，胆管壁僵硬，缺乏弹性，呈铅管状，失去正常肝内胆管的"垂柳"样的柔软、平滑的表现，肝内胆管细支显得稀少而达不到肝脏的边缘，呈所谓的"枯枝"或"剪枝"状。

Somehow I cannot picture Cherie with a pair of secateurs that she really knew how to use.

不知何故，我无法想象切丽手握剪枝夹的情景，她真的会用吗？

In the algorithm game tree method is used. The optimal location of chessman movement is searched by pruning and minimax value method.

五子棋博弈算法采用了博弈树的方法，应用了剪枝和极大极小值原理进行搜索寻找最优的下子位置。

HM-Miner uses the upper bound property to cut down search space,whereas HM-Two-Phase-Miner uses transaction-weighted downward closure property to achieve the same goal.

HM-Miner利用激励的上界特性剪枝，HM-Two-Phase-Miner则利用事务权重激励向下封闭特性剪枝。

The heuristic method emploies a genetic algorithm in reducing the redundant attributes of all attributes. Besides taking fitness function as its heuristic function for its selection operation, the genetic algorithm uses the attribute\'s information entropy to construct the heuristic function for its mutate operation, and in this way it markedly elevate the convergence speed of attribute reduction.

启发式方法采用遗传算法进行属性约简，除了存在于选择操作的适应度启发函数外，还在变异操作中以信息熵为基础构造了启发函数；穷举方法基于循环队列自底向上约简，通过剪枝有效地提高了属性约简集的穷举速度。

The penalty optimal brain surgeon is a post-training algorithm and it has extreme high complexity. The OBS oriented compute model implemented neural network training and OBS pruning simultaneously, by taking the OBS pruning case as a penalty term of neural network objective functions based on optimized structure of the regularization method included in the neural network training process. It both maintained the OBS's accuracy and had regularization method's high efficiency. Raised the generalization of neural network model.

最优脑外科过程是一种训练后网络剪枝算法，计算的复杂度非常高，通过把剪枝条件以惩罚项的形式纳入神经网络的训练目标函数中，把正则化方法的结构优化蕴涵于网络训练过程，构建面向最优脑外科过程的计算模型，实现网络训练过程和最优脑外科过程并行剪枝，既保持了最优脑外科过程的准确性，又具有正则化的高效性，提高了神经网络模型的泛化性能。

First, improved the heuristic cut-off algorithm, which combinate the filter algorithm and heuristic cut-off algorithm, speed up the execution.

第一，启发式剪枝改进算法将过滤算法和启发式剪枝算法相结合，加快了算法的执行速度。

Two new data structures TOPSIS-Tree and RELIS are devised to maintain potential significant itemsets and mined results, respectively. Moreover, three optimal strategies are exploited to reduce time and space consumption of the algorithms:(1) pruning impotent nodes in the newest basic window whenever a sliding window updates,(2) promoting support threshold during mining process dynamically, and (3) adjusting pruning threshold adaptively and heuristically.

设计概要结构TOPSIS-Tree和RELIS分别存储和记录流数据的摘要信息和当前滑动窗口的挖掘结果，并设计了三种优化策略用以提高算法的时空效率：(1)滑动窗口更新时剪枝最新基本窗口的无功节点；(2)挖掘过程中动态提升支持度阈值；(3)启发式自适应调整剪枝阈值。

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。
