+For multiclass classification problems, the algorithm will output a multinomial logistic regression
 model, which contains $K - 1$ binary logistic regression models regressed against the first class.
 Given a new data points, $K - 1$ models will be run, and the class with largest probability will be
 chosen as the predicted class.
