Model selection parameters for classification of constitutive sites against background

Parameter	Set of values	Optimal value
Weight degree kernel with shifts
Order	{1, 2 , … , 24}	8
Shift	{4, 8 , … , 48}	12
C	{0.177, 0.25 , … , 5.6}	1.4
Spectrum kernel
Order	{1, 2 , … , 24}	8
C	{0.177, 0.25 , … , 5.6}	5.6

Note: Model selection was performed on 20% of the data that was kept independent, and applying cross validation.
