For example, we have to detect spam mail (垃圾邮件), 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, “positive” data would be photos including a happy face, and “negative” data photos include a sad face. Once a classification boundary is learned, the computer can determine whether a certain data is positive or negative. However, the difficulty with this technology is that it requires both positive and 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 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 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 with 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 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. ” [语篇解读]　本文是一篇说明文。分类对我们的日常生活至关重要。然而在分类技术机器学习过程中， 分类既要积极的数据， 也需要消极的数据， 而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器学习如何只识别积极的数据。 1．How can the computer distinguish the positive data from the negative data? A．By learning the classification boundary. B．By updating the data collected regularly. C．By separating happy faces and sad ones. D．By introducing classification technology. 解析：A　[细节理解题。根据第一段最后一句可知， 计算机是通过学习分类边界来区分积极数据和消极数据的。] 2．Why is the example mentioned in Paragraph 2? A．To prove how important the positive data are. B．To confirm that data on customers are complete. C．To argue that retailers get their competitors' data. D．To explain why negative data are hard to acquire. 解析：D　[细节理解题。根据第二段第一句可知，在学习过程中， 这项技术既需要积极的数据， 也需要消极的数据， 而消极的数据在很多情况下是很难获得的， 进而后面举例说明了为什么消极的数据很难获得。] 3．What do the underlined words “new method” in Paragraph 3 refer to? A．Analyzing buying intention. B．Building a confidence score. C．Assessing the active rate of app users. D．Equipping the computer with confidence. 解析：B　[词义猜测题。根据画线词组前一句中 “but we have 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， 使用这种建立信心指数的新方法， 我们就可以让电脑只用积极的数据来学习， 故画线词组是指建立信心指数。] 4．What can be a suitable title for the text? A．The History of Classification Technology B．Smarter AI：Machine Learning without Negative Data C．Bigger Data：Computers Assisting Language Processing D．The Comparison between Positive Data and Negative Data 解析：B　[标题归纳题。通读全文可知， 分类对我们的日常生活至关重要。然而在分类技术机器学习过程中， 分类既要积极的数据， 也需要消极的数据， 而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器学习只识别积极的数据。] B There are some very good things about open education.This way of teaching allows the students to grow as people, and to develop their own interests in many subjects.Open education allows students to be responsible for their own education, as they are responsible for what they do in life.
