Support vector regression problem,
In support vector regression, the final decision coefficient alpha is zero, said not support vector, within the epsilon band, less than C greater than 0 in the epsilon, greater than C said outside the zone, but I do in the process of development, there will be little difference, such as alpha equals 0 should be within the belt, but he was in the band, although is not obvious, difference of very small, but I want to ask what is the reason? The internal and external network search no answer
