Online Coregularization for Multiview Semisupervised Learning
Table 2
Mean test error rates on the two-moons-two-lines synthetic data set. The error rates are reported for three different sparse approximations. For gradient ascent, we choose a decaying step size . The result shows that our derived online co-regularization algorithms achieve test accuracy comparable to offline co-regularization (CoLapSVM). The online co-regularization algorithms based on aggressive dual ascending procedures perform better than those based on gradient ascent.
