Better than previous state of the art on a standard machine learning dataset. Check some leaderboards here: http://rodrigob.github.io/are_we_there_yet/build/#datasets

What are you talking about? They build a 12x12 crossbar. The best you can do with it is to implement a single layer perceptron to classify 3x3 pixel patterns. Once they figure out how to scale it up, they will implement a larger network.
