One of the things that our brains excel at is the ability to recognize what things are, even when presented with an incomplete set of data. If we know only that an animal is sold in pet stores and stuffs food in its cheeks, for instance, we can be pretty certain that the animal in question is a hamster. Now, for the first time ever, researchers at the California Institute of Technology (Caltech) have created a DNA-based artificial neural network that can do the same thing ... albeit on a very basic level. They believe that it could have huge implications for the development of true artificial intelligence.
The neural network is made up of just four artificial neurons, as opposed to the human brain's 100 billion real ones.
