Ten simulation datasets and their input features.

Dataset	Function	No converted input features	Converted input features
1	Y = |X 1 − X 2| = Z 1	{X 1, X 2}	{Z 1}
2	Y = |X 1 − X 2| + |X 3 − X 4| = Z 1 + Z 2	{X 1, X 2, X 3, X 4}	{Z 1, Z 2}
…	…	…	…
10	Y = |X 1 − X 2| + |X 3 − X 4| + … + |X 19 − X 20| = Z 1 + Z 2 + … + Z 10	{X 1, X 2, X 3, X 4,…, X 19, X 20}	{Z 1, Z 2,…, Z 10}

Here, X is assigned with random values between 0 and 1, and Y is binarized with the median. Sample size for each dataset is 200.
