Thanks doclogan, scikit-learn seems to be a very good package. When I look into the parameters for the kernel = "poly", they talk about gamma (gamma*u'*v + coef0)^degree).
Gamma is not clearly defined in our formula and it is multiplicating the inner product. Are you setting the values 1 to gamma and coeff0 ? Any other parameters that I should pay attention (other than the degree = 2)?
