①As missing children get older,they become quite different from the faces in their last﹣known photographs,which makes finding the really difficult. Now AI(人工智能)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

"Even with a recent face image of a child,it is quite hard for a human to recognize(辨认),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
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
⑥Deb's next goal(目标 )is to make the age gap wider. His team also hopes to develop an app to fight against the sale of children.
