LED Display Domain data set 1: Description. This simple domain contains 7 Boolean attributes, one for each light-emitting diode of a 7-segment display. The task is to determine which digit is been shown in the display. The problem would be easy if not for the introduction of noise. In this case, each attribute value has the 10% probability of having its value inverted. This data set is a sample of 500 instances obtained from the original data generator. 2: Type.
