Recently,A study conducted by researchers from RMIT University in Melbourne,Australia showed that bees could perform arithmetic operations like addition and subtraction (減法). Solving math problems requires a plex level of involving the mental management of numbers,longterm rules and shortterm working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence,particularly in improving rapid learning. RMIT’s Professor Adrian Dyer said numerical (數(shù)字的) operations like addition and subtraction are plex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your longterm memory,while mentally using skillfully a set of given numbers in your shortterm memory,” Dyer said. “On top of this,bees also used their shortterm memories to solve arithmetic problems,as they learned to recognize plus or minus as abstract concepts. ”The findings suggest that advanced numerical cognition (認知) may be found much more widely in nature among nonhuman animals than previously suspected. “If math doesn’t require a massive brain,there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer. Many species can understand the difference between quantities and use this to search for food,make decisions and solve problems. But numerical cognition,such as exact number and arithmetic operations,requires a more plex level of processing. Previous studies have shown some primates (靈長目動物),birds,babies and even spiders can add and subtract. The new research,published in Science Advances,adds bees to that list. 【語篇概述】本文是一篇科普文章。RMIT大學的研究人員發(fā)現(xiàn)了蜜蜂能做基本的數(shù)學運算。此前的研究表明,一些靈長目動物、鳥類、嬰兒甚至蜘蛛都可以做加減法運算。發(fā)表在《科學進展》雜志上的這項新研究將蜜蜂也列入了這一名單。28.
