YerevaNN

research lab

YerevaNN /jɛɾɛvɑnˈɛn/ is a machine learning research center based in Yerevan, Armenia. Read more about our plans to establish an AI Institute. YerevaNN is a non-profit funded by research grants, academic partnerships and generous donations. Here are the easiest ways to support us.
