Due to the increase in the amount of digital data, effective data classification plays an increasingly important role in real world applications. For instance, a retrieval application would use a trained classification model to retrieve relevant results with respect to a query. To ensure reliable performance, the classifier must be trained using labeled...

Due to the tremendous increase in the amount of digital data, effective large scale data classification is playing an increasingly important role. In active learning algorithms a ?classifier? is used to classify the unlabeled data. To ensure reliable performance of the classifier, it must be trained using a number of labeled examples, or the...
