Abstract
An unlabeled sample is classified using clustering. A set of samples containing labeled and unlabeled samples is established. Values of features are gathered from the samples contained in the datasets and a subset of features are selected. The labeled and unlabeled samples are clustered together based on similarity of the gathered values for the selected subset of features to produce a set of clusters, each cluster having a subset of samples from the set of samples. The selecting and clustering steps are recursively iterated on the subset of samples in each cluster in the set of clusters until at least one stopping condition is reached. The iterations produce a cluster having a labeled sample and an unlabeled sample. A label is propagated from the labeled sample in the cluster to the unlabeled sample in the cluster to classify the unlabeled sample.
