Question

    Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.

For species(物种)like chimpanzees, which have complex social lives and live for many years，getting photos of their behavior taken from short-term field research can only tell us so much，” says Dan Schofield， researcher and DPhil student at Oxford University’s Private Models Lab, School of Anthropology. “By taking advantage of the power of machine learning to unlock large video files , it makes it possible to measure behavior over the long term. ’’

The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea,West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality.

“Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible,” says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science ,University of Oxford .” Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预)，saving hours of time. ”

The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.

1.What is the purpose of developing the new soft?

A.To save wildlife researchers’ time spent in the labs.

B.To keep track of wildlife conservationists' behaviors.

C.To protect chimpanzees and help them to live longer .

D.To recognize and track the faces of wild chimpanzees.

2.What does the underlined word “it” in paragraph 2 refer to?

A.Getting photos. B.Analyzing videos.

C.A powerful machine D.The new AI software.

3.What does paragraph 4 mainly talk about?

A.The working principle of the new software. B.Some limitations of using the new software.

C.The unique advantages of the new software. D.Controversial attitudes to the new software.

4.What can be known from the last paragraph?

A.Technology advance is the final goal of science

B.The new software won’t just be applied to chimpanzees.

C.AI systems are widely used in the wildlife sciences.

D.The application of the new technology isn’t easy.
