Mean test error rates on different datasets. The error rates are reported for three different step size selection methods in the form of stationary step size/aggressive step size/decreasing step size. The result shows that our derived online MR algorithms achieve test accuracy comparable to offline MR. Specially, the experiments on two rotating spirals show that our online MR is able to track the changes in the sequence and maintain a much better error rate compared to offline MR. The performances of online MR algorithms are competitive with those of the state-of-the-art offline MR.
