Taking inspiration from other technology adapted for recognizing primates(灵长目动物) and bears, Krista Ingram, a biologist at Colgate University, developed SealNet, the software that uses deep learning and a convolutional neural network(卷积神经网络) to tell one seal face from another. The team had to train their software to identify seal faces. "I give it a photograph, it finds the face, and clips it to a standard size," says Ingram. They tested the software using 406 different seals and found that SealNet could correctly identify the seals' faces 85 percent of the time. The team has since expanded its database to include around 1,500 seal faces. As the number of seals logged in the database goes up, so does the accuracy of the identification, Ingram says. As with all tech, however, SealNet is not always infallible. The software saw seal faces in other body parts, vegetation, and even rocks. In one case, Ingram and her students did a double take at the uncanny(不可思议的) resemblance between a rock and a seal face. Ingram points to site fidelity(忠诚) as an aspect of seal behavior that SealNet could shed more light on. The team's trials indicated that some harbor seals return to the same sites year after year. Increasing scientists' understanding of how seals move around could strengthen arguments for protecting specific areas, says Anders Galatius, an ecologist at Aarhus University in Denmark who was not involved in the project. 11.What is the main function of SealNet A.
