Three years and thousands of images later,the behavioral researcher and postdoctoral student at the University of Victoria has partnered with two software developers living in Silicon Valley and a grizzly research centre in Alaska to develop facial recognition technology used to identify the bears. "They don't have distinctive markings on their bodies,"said Clapham,whose interest in this technology sprang from the need to "identify and recognize individual bears over time"as part of her behavioral research over the last 11 years. Bears grow and shrink a lot depending on the season,and their appearance changes frequently during their 20-to 25-year-long lifespans.Clapham began to wonder if AI might be able to solve her problem in the same way the technology recognizes people's faces. Now,she says,the open-source BearID software can be used and adapted by anyone and could have huge hints for understanding the animals'behaviour and avoiding bear-human encounters. In relation to the technology based on human facial recognition,Ed Miller and his partner Mary Nyugen are the software developers from California who connected with Clapham in an online forum for conservation technology in late 2017. The pair were looking for photos of bears "for fun"as a way to learn more about recognition software,and so they connected with Clapham to offer their expertise ( in adapting artificial intelligence. "The technology we're using is based on the same software used to recognize humans," said Miller,who added that human identification is far easier,as there are millions of images the software can learn from. "We need lots of images of individual animals to tell the system which bear is which," said Clapham,who
