SOMFlow: Guided Exploratory Cluster Analysis with Self-Organizing Maps and Analytic Provenance

Dominik Sacha, Matthias Kraus, Jurgen Bernard, Michael Behrisch, Tobias Schreck, Yuki Asano, Daniel A. Keim
2018 IEEE Transactions on Visualization and Computer Graphics  
We present a multi-stage Visual Analytics (VA) approach for iterative cluster refinement together with an implementation (SOMFlow) that uses Self-Organizing Maps (SOM) to analyze time series data.  ...  We conducted two pair analytics experiments together with a subject matter expert in speech intonation research to demonstrate that the approach is effective for interactive data analysis, supporting enhanced  ...  BACKGROUND ON SELF-ORGANIZING MAPS We chose the SOM algorithm (also known as Kohonen Maps [31] ) as a fundamental approach to automatically generate data overviews.  ...
