Closes #279.
Current Behavior
We had
predict_multinomial_probit, but it does not account for over and underflows and does the same assoftmax.Solution / Implementation
Use
scipy.special.softmaxwhich uses the log-sum-exp trick. Theguvectorizeis not necessary as the dot product and the scipy function are almost not measurable in line profilings.
