Suppose the softmax regression technique was applied to classify a data set that contains three classes C1,C2,C3. We minimize the objective function minimizef(w^)=P1p=1P[log(j=13ew^jTx^p)w^ypTx^p] over the training data set {(xp,yp),p=1,2,,P} where xpR21 and yp{1,2,3}, The minimizer is w^=[215140312]T (The sub-models are stacked in the order of w^1,w^2,w^3 )
