PLD: A Distillation Algorithm for Misclassified Documents
We observed that in interactive text classification, user tends to point out only the misclassified documents, not the correct ones. It is unlikely that a user would be diligent enough to identify all the misc...

Categorical Data Visualization and Clustering Using Subjective Factors
A common issue in cluster analysis is that there is no single correct answer to the number of clusters, since cluster analysis involves human subjective judgement. Interactive visualization is one of the metho...
