Description methods that employ color histograms use a quantitative representation of the distribution of color intensities 使用色彩直方圖的描述法用色強(qiáng)度分布的定量表示。
In this paper , we give a quantitative representation of the ability of knowledge ' s classification , and provide a novel representation of knowledge , that is , it can be expressed by expectation 本文對(duì)知識(shí)的分類能力給予了量化,提出了一種新的知識(shí)表示方法,稱為數(shù)學(xué)期望表示法,我們利用數(shù)學(xué)期望來定量地表示知識(shí)的分類能力。
According to the deficiencies of current research in domain knowledge base , this paper classifies the knowledge in domain knowledge base on the basis of the book organization , brings forth a transferring computation method of relationships between knowledge points , which is based on the quantitative definition of relationships between knowledge points , and builds a quantitative representation mode of knowledge base . meanwhile , this paper proposes the navigating strategy , testing strategy and diagnosing strategy , which can provide method and foundation for the development of icai system 針對(duì)當(dāng)前領(lǐng)域知識(shí)庫研究中存在的不足,本文按照書本的組織對(duì)領(lǐng)域知識(shí)庫中的知識(shí)進(jìn)行劃分,從知識(shí)的組織角度和依賴角度對(duì)知識(shí)點(diǎn)之間的關(guān)系進(jìn)行定量定義,提出了知識(shí)點(diǎn)關(guān)系傳遞計(jì)算方法,建立了一個(gè)知識(shí)庫定量表示模型,并在此基礎(chǔ)上提出了基于組織關(guān)系和依賴關(guān)系的導(dǎo)航策略、測試策略和診斷策略,從而為智能計(jì)算機(jī)輔助教學(xué)系統(tǒng)的開發(fā)提供了方法和依據(jù)。
The knowledge model was developed based on the dynamic relationships between crop and environments , and quantitative representation of the temporal and spatial variation in crop growth and management indices . this provided the decision - making of dsspf with interpretation and wide applicability , thus overcoming the shortcomings of the traditional expert system with strong empiricism and localization 知識(shí)模型是基于作物與環(huán)境的動(dòng)態(tài)關(guān)系,通過定量描述作物生育和管理指標(biāo)的時(shí)空規(guī)律,從而使dsspf中的管理決策支持具有解釋性和廣適性,有效解決了專家系統(tǒng)決策中地域性和經(jīng)驗(yàn)性較強(qiáng)的這一難題。
