Based on the principle of the above reform of instruction , prof . zhuxinming and prof . simon put up with theory of learning from examples and through problem solving after ten years " corporative research 本著這一教學(xué)改革的思想,朱新明教授和simon教授,進(jìn)行10多年的協(xié)作研究提出了示例演練教學(xué)法。
Neutral network can learn from examples and has a strong ability of studying . however , it is a set of no models . to make neutral network " s results satisfied , it needs a lot of trained data 神經(jīng)網(wǎng)絡(luò)可以從例子中學(xué)習(xí),具有很強(qiáng)的自適應(yīng)學(xué)習(xí)能力,但由于神經(jīng)網(wǎng)絡(luò)模型是無(wú)模型的預(yù)報(bào)器,因此要使學(xué)習(xí)結(jié)果滿意,需要很多數(shù)據(jù)進(jìn)行訓(xùn)練。
We look at the problem of learning from examples as the problem of multivariate function approximation from sparse chosen data , and then consider the case in which the data are drawn , instead of chosen , according to a probability measure 并檢視稀疏精選值中多變量函數(shù)近似法等這些從實(shí)例學(xué)習(xí)法所發(fā)現(xiàn)的問(wèn)題,然后根據(jù)機(jī)率衡量,審思隨機(jī)獲得資料而非選定資料的案例。
Most people think so , and say nothing of self - determining learning from the web . so what is wll ( webcourse lying on lfetps ( learning from examples and through problem solving ) ) and the significance of it were discussed first 因此本文第一部分分析了當(dāng)前國(guó)內(nèi)中小學(xué)網(wǎng)上課程存在的問(wèn)題,并從示例學(xué)習(xí)網(wǎng)上課程的定義及其特點(diǎn)等方面論述了示例學(xué)習(xí)網(wǎng)上課程的重要研究意義。
But , fuzzy decision tree induction is an important way for learning from examples with fuzzy representation . it is a special case of fuzzy decision tree induction extracting rules from the data , which have symbol features and crisp classes 而模糊決策樹(shù)歸納是從具有模糊表示的示例中學(xué)習(xí)規(guī)則的一種重要方法,從符號(hào)值屬性類(lèi)分明的數(shù)據(jù)中提取規(guī)則可視為模糊決策樹(shù)歸納的一種特殊情況。
The instruction based on this theory systematically combine the " learning from examples " and " learning by doing " . the fundamental form of the study model guided by the theory of learning from examples and solving by problems benefits the quality education 示例演練教學(xué)法將“例中學(xué)”和“做中學(xué)”有機(jī)地結(jié)合起來(lái),以“示例演練”作為基本的學(xué)習(xí)形式,是一種有利于素質(zhì)教育的教學(xué)模式。
Based on large numbers of train examples , we adopt learning from examples approach which implement produce rules by using extended ocat algorithm to realize classification of text . at the same time , we put forward rules for special word to calculate the credibility of text 我們采用實(shí)例學(xué)習(xí)方法,在大量訓(xùn)練實(shí)例的基礎(chǔ)上,將改進(jìn)的用于邏輯規(guī)則提取的ocat挖掘算法用于文本分類(lèi)規(guī)則的提取,分別產(chǎn)生針對(duì)正例集和反例集的識(shí)別規(guī)則,對(duì)文本進(jìn)行二分分類(lèi)。
2 . the traditional instruction model of " one knife ' s cutting " are evolved to classified advance and entire progress . this evolve promotes students in different level study most efficiently by the web - based learning from examples and through problem solving , and exert the greatest potential with the best situation 2 、變傳統(tǒng)的“一刀切”的課堂教學(xué)模式為分類(lèi)推進(jìn)、共同進(jìn)步,讓不同層次的學(xué)生在網(wǎng)上示例演練教學(xué)環(huán)境下都以自己最好的狀態(tài)進(jìn)行學(xué)習(xí),將自己的潛能最大程度地發(fā)揮,進(jìn)行最有效地學(xué)習(xí)。
Thirdly , by introducing fuzzy theory into system evaluation , evaluating student , teaching , course resource , and function of whole system . fourthly , making use of learning from examples based on information theory , machine learning algorithm is improved and machine learning decision tree is realized . finally , on reasoning mechanism , combining means of two classes reasoning is taken 第三,在系統(tǒng)評(píng)價(jià)中引入了模糊理論,對(duì)學(xué)生、教學(xué)、課程資源以及系統(tǒng)的整體功能進(jìn)行了評(píng)價(jià);第四,采用基于信息論的示例學(xué)習(xí),改進(jìn)了決策樹(shù)學(xué)習(xí)算法,并建立了機(jī)器學(xué)習(xí)決策樹(shù);第五,在推理機(jī)制上,采取兩級(jí)推理相結(jié)合的方法進(jìn)行推理,即用基于語(yǔ)義網(wǎng)絡(luò)的模糊推理確定教學(xué)序列,用基于產(chǎn)生式規(guī)則的推理確定教學(xué)方法,并給出了詳細(xì)的推理算法。
From the knowledge - database , students " model - teachers " model and supportive system , the system model of the web - based learning from examples and through problem solving come into being . on the basis of the model , an applied system called " the study gardening of the web - based learning from examples and through problem solving are put up with choosing the algebra in the first - grade junior high school 基于以上兩個(gè)目的,本課題探索了網(wǎng)上示例演練教學(xué)模式,從知識(shí)庫(kù)、學(xué)生模型、教師模型、支持系統(tǒng)四個(gè)方面入手,提出了網(wǎng)上示例演練教學(xué)系統(tǒng)模型。并據(jù)此模型,選擇初中一年級(jí)代數(shù)為教學(xué)內(nèi)容,設(shè)計(jì)開(kāi)發(fā)了一個(gè)網(wǎng)上示例演練教學(xué)系統(tǒng)實(shí)例? ?網(wǎng)上示例演練教學(xué)學(xué)苑。
