20、assifying things is critical for our daily lives.For example，we have to detect spam mail(垃圾郵件)，false political news. When we use AI，such tasks are based on “classification technology” in machine learning having the computer learn，using the boundary separating positive and negative data.For example，“

21、positive” data would be photos including a happy face，and “negative” data photos that include a sad face.Once a classification boundary is learned，the computer can determine whether certain data are positive or negative.However，the difficulty with this technology is that it requires both positive an

22、d negative data for the learning process，and negative data are not available in many cases.For instance，when a retailer(零售商) is trying to predict who will make a purchase，they can easily find data on customers who have purchased from them (positive data)，but it is basically impossible to obtain data

23、 on customers who have never purchased from them(negative data)，since they do not have access to their competitors data.According to lead author Takashi Ishida from RIKEN AIP，“Previous classification methods could not cope with the situation where negative data were not available，but we have made it

24、 possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users.Using our new_method，we can let computers learn a classifier only from positive data equipped wit

25、h confidence.”According to Ishida，“This discovery could expand the range of applications where classification technology can be used.Even in fields where machine learning has been actively used，our classification technology could be used in new situations where only positive data can be gathered due

26、 to data regulation or business constraints(限制)In the near future，we hope to put our technology to use in various research fields，such as natural language processing，computer vision，robotics，and bioinformatics.”【語(yǔ)篇解讀】分類對(duì)我們的日常生活至關(guān)重要。然而在分類技術(shù)機(jī)器學(xué)習(xí)過(guò)程中，分類既需要積極的數(shù)據(jù)，也需要消極的數(shù)據(jù)，而消極的數(shù)據(jù)在很多情況下是很難獲得的?，F(xiàn)在科學(xué)家能用分類技術(shù)使機(jī)器

28、s learned，the computer can determine whether certain data are positive or negative”可知，一旦學(xué)習(xí)了分類邊界，計(jì)算機(jī)就可以確定某些數(shù)據(jù)是積極的還是消極的，由此可知，計(jì)算機(jī)是通過(guò)學(xué)習(xí)分類邊界來(lái)區(qū)分積極數(shù)據(jù)和消極數(shù)據(jù)的。6Why is the example mentioned in Paragraph 2?ATo prove how important the positive data are.BTo confirm that data on customers are complete.CTo argue th

30、的數(shù)據(jù)，也需要消極的數(shù)據(jù)，而消極的數(shù)據(jù)在很多情況下是很難獲得的，進(jìn)而后面舉例說(shuō)明解釋了為什么消極的數(shù)據(jù)很難獲得。7What do the underlined words “new method” in Paragraph 3 refer to?AAnalyzing buying intention.BBuilding a confidence score.CAssessing the active rate of app users.DEquipping the computer with confidence.B推理判斷題。根據(jù)文章的第三段，尤其是畫(huà)線詞組前一句中的“but we have

31、 made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users”可推知，畫(huà)線詞組所在句表示使用這種建立信心指數(shù)的新方法，我們就可以讓電腦只用積極的數(shù)據(jù)來(lái)學(xué)習(xí)，故畫(huà)線詞組是指建立信心指數(shù)。8What can be a suitable titl
