Unsupervised Prediction of Citation Influences

Unsupervised Prediction of Citation Influences

Posted in Science

Publication repositories contain an abundance of information about the evolution of scientific research areas. We address the problem of creating a visualization of a research area that describes the flow of topics between papers, quantifies the impact that papers have on each other, and helps to identify key contributions. To this end, we devise a probabilistic topic model that explains the ge...

Visualising the Cluster Structure of Data Streams

Visualising the Cluster Structure of Data Streams

Posted in Science

The increasing availability of streaming data is a consequence of the continuing advancement of data acquisition technology. Such data provides new challenges to the various data analysis communities. Clustering has long been a fundamental procedure for acquiring knowledge from data, and new tools are emerging that allow the clustering of data streams. However the dynamic, temporal components o...
