The results obtained by this method prove the validity of the entropy model of sliding window ( emsw ) in other aspect 用該模型得出的結(jié)果證實(shí)了滑動(dòng)窗口信息熵模型得出的結(jié)果的正確性。
In this paper, we present a new method on feature extraction which uses hownet as semantic resource, and use maximum entropy model to realize it 本文提出了一種使用知網(wǎng)作為語義資源選取分類特征,并使用最大熵模型進(jìn)行分類的新方法。
Popular choices are the exponential and inverse power functions typically used in entropy models, and the gamma function often recommended in us planning practice 大多數(shù)的選擇是指數(shù)和熵模型中常用的反冪函數(shù),在美國的計(jì)劃編制中通常建議采用函數(shù)。
Thirdly, while constructing email presenting model, features extracted from email header are collected . maximum entropy model is applied to email categorization 再次,針對(duì)郵件的特點(diǎn),在構(gòu)造郵件表示模型時(shí),從郵件頭部字段抽取了一系列的郵件特征用以分類。
As the expriment result shows, we can use the range of misclassification rate ( which the maximum entropy model supports ) as the indicator of whether a process is attacked 最后,我們運(yùn)用最大熵原理建立進(jìn)程調(diào)用序列的最大熵(分類)模型,運(yùn)用模型預(yù)測(cè)系統(tǒng)調(diào)用和利用誤分類率為檢測(cè)指標(biāo),以達(dá)到更好地檢測(cè)入侵目的。
2 . a new framework, named information entropy model of sliding window ( iemsw ), was proposed to effectively analyze the structural information contained in the 3'- utr sequences around the polyadenylation site . 3 為有效地分析水稻3-utr序列剪切位點(diǎn)上下游序列中的信息結(jié)構(gòu),提出了一個(gè)新的分析框架,即dna序列的滑動(dòng)窗口信息熵模型。
In this paper, the expectation of logarithm-entropy model is established to measure the risk of successive investment, and the optimal portfolio of a number of stocks selected by this model in shanghai securities market is obtained 文章建立了對(duì)數(shù)期望熵模型來度量投資的風(fēng)險(xiǎn),并以滬市證券市場(chǎng)進(jìn)行實(shí)證研究,利用該模型選出適當(dāng)數(shù)量的股票進(jìn)行優(yōu)化組合。
