In issue332, data points from Gaussian distribution (base [1, 1, 1]) and points from base [9, 9, 9] can't not be well separating using softmax regression. The implementation of softmax regression haven't add the intercept term, which means the hypothesis space only contains 3-d planes crossing the origin. This patch try to fixed this problem by adding the intercept term to it.
