Data Set Information:

This simple domain contains 7 Boolean attributes and 10 concepts, the set of decimal digits. Recall that LED displays contain 7 light-emitting diodes -- hence the reason for 7 attributes. 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.

It's valuable to know the optimal Bayes rate for these databases. In this case, the misclassification rate is 26% (74% classification accuracy).


Attribute Information:

-- All attribute values are either 0 or 1, according to whether the corresponding light is on or not for the decimal digit.
-- Each attribute (excluding the class attribute, which is an integer ranging between 0 and 9 inclusive) has a 10% percent chance of being inverted.
