| Abstract(in English) | A simple label propagation technique is presented for semi-supervised learning of pattarn classifiers. In our technique, label is propagated on a sparse unweithed graph called the kNN graph. This propagation can be executed with only integer computation and stops in finite steps. Our method is therefore faster than the conventional label propagation methods dealing with real numbers and with slow convergence. We develop an unsupervised learning method exploiting this label propagation procedure and apply it to select data to be labeled in our semi-supervised learning. The performance of the present method is examined for a synthetic dataset and some real datasets. |
