XOR input samples were generated by using a threshold function for 1000 values from a uniformly distributed pseudorandom number generator. The threshold function had a threshold level of 0.5. Sample = ( 1 ; value > 0:5 0 ; value >= 0:5

value is 1 when sample value greater than 0.5 and 0 when it is less than or equal to 0.5
