About the development
hananona app is an application developed by Software Technology and Artificial Intelligence Research Center (STAIR Lab.), Chiba Institute of Technology.  Children learn the names of things while being taught the names of the things they see from the people around them. The latest Artificial Intelligence research has made it possible to learn the names of things by showing many examples to a computer just like children do. The key is a large amount of training data and deep learning. Applying this latest theory, we developed Artificial Intelligence using four hundreds thousand flower photos.
