Ai (chimpanzee)
Ai is a female chimpanzee currently living at the Primate Research Institute of Kyoto University. She is known for being the principal subject of the Ai project, a research program started in 1978 by Tetsuro Matsuzawa which is aimed at understanding chimpanzee cognition through computer interface experiments. The Ai project includes tests for numerical competency, color-to-symbol matching ability, and audio-to-image matching and recognition. Over the years, the Ai project has grown to include a 14-member community of chimpanzees who reside in a state-of-the-art facility at KUPRI.
