①As missing children get older,they become quite different from the faces in their last-known photographs,which makes finding them really difficult.Now AI can make it easier to match any found children to those old photos.
②Police can use software(软件) to age photos of missing people,but it seems to work best in adults,as age-related changes of adult faces are much easier to predict and to make.
③Unlike adults,the faces of children change greatly as time goes by,and matching photos of found children to old images(画像) in a database(数据库) of missing children is difficult.“Even with a recent face image of a child,it is quite hard for a human to recognize(辨认),visually,who the child is from a large data set of child face images,” says Debayan Deb at Michigan State University.
④Now Deb and his teammates have created an algorithm(算法) to work out the problem.They created a face-recognition algorithm on data sets,which have images of nearly 1,000 children between 2 and 18 years old.And they took photos of them at least four times over a period of six years.
⑤AI learned to match recent photographs of children with images taken 2.5 years earlier.The correct matching rate can be 80 percent.With one year between the two photographs,it was 90 percent correct at recognizing faces.This dropped to 73 percent after three years.The new AI might help to improve accuracy(准确性) of this kind of software,too.
⑥Deb's next goal is to make the age gap wider.His team also hopes to develop an app to fight against the sale of children.
( )14.What does the underlined word “them” in Paragraph 1 refer to?
A.School children.
B.The missing children.
C.The children's faces.
D.The last-known photos.
B
( )15.Why does Deb's team do the research according to Paragraphs 3 and 4?
A.To make it easier to match photos of found children with old photos.
B.To build a database to find the missing children.
C.To help the police change and improve their software.
D.To tell the difference between adults and children.
A
( )16.What can we infer from the passage?
A.Deb's team has already made the age gap wider.
B.AI can help to improve accuracy of matching rate.
C.Deb and his team will still work hard to develop a new app.
D.It is hard to recognize a found child even with a recent image.
