Artificial intelligence identifies plant species by looking at them

Machine learning algorithms have successfully identified plant species in massive herbaria just by looking at the dried specimens. According to researchers, similar AI approaches could also be used identify the likes of fly larvae and plant fossils. There are roughly 3,000 herbaria in the world, hosting an estimated 350 million specimens -- only a fraction of which has been digitized. But the swelling data sets, along with advances in computing techniques, enticed computer scientist Erick Mata-Montero of the Costa Rica Institute of Technology in Cartago and botanist Pierre Bonnet of the French Agricultural Research Centre for International Development in Montpellier, to see what they could make of the data. Researchers trained... algorithms on more than 260,000 scans of herbarium sheets, encompassing more than 1,000 species.
