查询词典 drift boat

In a database the concept of an example might change along with time which is known as concept drift When the concept drift the classification model built by use of old data is unsuitable for classify new data Therefore concept drift has become a hot issue in data mining in recent years Although many algorithms had been proposed to resolve this problem they can not provide users with the reason of concept drift However a user might be very interested in such rules For example doctors want to find what makes disease change; researchers want to know the reason of the variety of the weather; and decision makers would like to understand why a customer's shopping habit change In this thesis we propose a Concept Drift Rule mining Tree called CDR-Tree to solve this problem CDR-Tree can not only find the rule of concept drift also build the prediction model for both old and new data at the same time

无论在大型资料库或现实生活中，同一资料样本的概念有可能会随著时间的递移而改变，也就是产生所谓的概念漂移。当样本发生概念漂移时，由旧有资料所建构的分类模组将不再适用於预测新获得的资料，因此，近年来概念漂移已成为资料探勘中一项热门的研究议题。虽然已有？多学者提出不同的技术来解决概念漂移的问题，但是这些方法都是利用修正或重建的方式来产生适合新资料的预测模组，并无法提供造成概念漂移的原因。然而对使用者而言，其感兴趣的可能正是这些引起概念漂移的规则，如医生可能想了解引起疾病变化的主因、学者会想要知道气候转变的规则、或是决策者想找出顾客购物习惯改变的因素等。因此，本论文提出概念漂移规则探勘树( Concept Drift Rule mining Tree )，简称CDR-Tree，来解决这个问题。CDR-Tree不但能探测出造成概念漂移的主要原因，亦能同时建立新旧资料的预测模组以供决策者运用使用。

The experiment shows that,there is phase drift of low frequency in the digital image seriel acquired by CCD camera and frame grabber,different CCD has different drift characteristic and level;the phase drifts are not identical even in the same image line,the phase drift of neighboring locations in an image line has distinct correlation;the drift levels ...

实验表明：经 CCD Camera和图像卡采集的数字图像序列中存在着低频的图像抖动，即位相漂移。而且不同的 CCD Camera具有不同的漂移特点和程度，甚至在同一个图像行内的漂移也不完全一致。一般在图像行内相近的位置之间，位相漂移有明显的相关性，不同的图像行之间的漂移的程度相同，但没有相关性。最后本文还给出了一种位相漂移的修正方法

And E.N.E: Had they seen the Island, as I must necessarily suppose they did not, they must, as I thought, have endeavour'd to have sav'd themselves on Shore by the Help of their Boat; but their firing of Guns for Help, especially when they saw, as I imagin'd, my Fire, fill'd me with many Thoughts: First, I imagin'd that upon seeing my Light, they might have put themselves into their Boat, and have endeavour'd to make the Shore; but that the Sea going very high, they might have been cast away; other Times I imagin'd, that they might have lost their Boat before, as might be the Case many Ways; as particularly by the Breaking of the Sea upon their Ship, which many Times obliges Men to stave, or take in Pieces their Boat; and sometimes to throw it over-board with their own Hands: Other Times I imagin'd, they had some other Ship, or Ships in Company, who upon the Signals of Distress they had made, had taken them up, and carry'd them off: Other whiles I fancy'd, they were all gone off to Sea in their Boat, and being hurry'd away by the Current that I had been formerly in, were carry'd out into the great Ocean, where there was nothing but Misery and Perishing; and that perhaps they might by this Time think of starving, and of being in a Condition to eat one another.

如果他们发现这个小岛，我想他们一定会用船上的救生艇竭尽全力划到岸上来的。但看来他们一定没有看到小岛，只是鸣枪求救，尤其是他们看到我燃起的火光后，更是多次放枪。由此我头脑里出现了种种设想。首先，我想到，他们看到我点燃的火光后，必然会下到救生艇里拼命向岸上划来，但由于风急浪高，把他们刮走了。一会儿我又猜想，也许他们的救生艇早就没了，这种情况是经常发生的。当大船遇到惊涛骇浪时，水手们往往不得不把船上的救生艇拆散，甚至干脆扔到海里去。过会儿我又想，也许与他们结伴同行的船只，在见到他们出事的信号后，已把他们救起来带走了。我又想到，说不定他们已经坐上救生艇，可是遇到了我上次自己碰上的那股急流，给冲到大洋里去了。到了大洋里，他们可就糟了，那是必死无疑的。说不定这会儿他们都快饿死了，甚至可能正在人吃人呢！

As soon as they got to the Place where their other Boat lay, they run their Boat in to the Beach, and came all on Shore, haling the Boat up after them, which I was glad to see; for I was afraid they would rather have left the Boat at an Anchor, some Distance from the Shore, with some Hands in her, to guard her; and so we should not be able to seize the Boat.

那批人来到头一只小船停泊的地方，马上把他们自己的小船推到沙滩上，船上的人也通通下了船，一起把小船拉到岸上。看到这一情况，我心里非常高兴。因为我就怕他们把小船在离岸较远的地方下锚，再留几个人在船上看守。那样我们就没法夺取小船了。
