The result is a tree structure with the "root" on the left and various payoffs on the right. Probabiliti 判定树提供决定和偶发事件依顺序连接从左到右的一个正式结构。 决定、偶发事件和最终结果由结代表并且由分支连接。 结果是一个树结构与“根”在左和各种各样的结局在右边。 事件发生和结局的可能...
Tree-ring chronologies underpin the majority of annually-resolved reconstructions of Common Era climate. However, they are derived using different datasets and techniques, the ramifications of which have hitherto been little explored. Here, we report the
AIM: To analyze the cost-effectiveness of the diagnosis of solitary pulmonary nodule(SPN) in China. METHODS: Decision analysis models were constructed to assess the cost-effectiveness of four strategies for the management of SPN: computed tomography(CT) alone, CT plus CT-guided automated cutting ...
The experimental results reveal that i+Learning method offers the promise of making decision trees a more powerful, flexible, accurate and valuable paradigm, especially in medical data mining community. 展开 关键词: Medical data mining Incremental learning Learning regarding attributes Decision tree ...
This paper describes a system which uses a decision tree to find and classify names in Japanese texts. The decision tree uses part-of-speech, character type, and special dictionary information to determine the probability that a particular type of name opens or closes at a given position in th...
archaeological research makes it a main task to find out the relationship among archaeological data and,accordingly,to study the hidden rules of social and historical development.The application of data mining to archaeology follows the trend.Decision-tree is a typical sorting arithmetic in data ...
These examples provide an overview of a typical assessment, which can benefit from utilizing a decision tree. Once all of the important variables are determined, these decision trees become very complex. However, these instruments are often an essential tool in theinvestment analysisor management deci...
Decision tree methods in pharmaceutical research. 来自 Semantic Scholar 喜欢 0 阅读量: 29 作者: Paul E. Blower, Kevin P. Cross 摘要: Decision trees are among the most popular of the new statistical learning methods being used in the pharmaceutical industry for predicting quantitative structure-...
Such applications have also been discussed in the context of MPEG-7. In our method the extracted features from three visual descriptors are logically combined using a decision tree to produce a reliable recognition. The results demonstrate a high identification rate based on a large collection of ...
