11. The choice of free parameters is somewhat arbitrary. 12. When measuring time in substitutions ( \ mu = 1 ) only 8 free parameters remain. 13. The number of free parameters in a nondimensionalized form of a system increases with its order. 14. Note that this model has an additional free parameter , namely the variance of the normal variable. 15. Since there are two free parameters , at most only two coefficients can be made to equal unity. 16. The Lorentz transformations, up to a nonnegative free parameter , can be derived without first postulating the universal lightspeed. 17. Note that only " three " arguments are needed since the Lagrangian itself only has three free parameters . 18. The bandwidth of the kernel is a free parameter which exhibits a strong influence on the resulting estimate. 19. A convolution operation on small regions of input is introduced to reduce the number of free parameters and improve generalization. 20. Once established, the axioms narrow the possible scale-space representations to a smaller class, typically with only a few free parameters .
