Information Retrieval Perspective to Interactive Data Visualization [article]

Jaakko Peltonen, Max Sandholm, Samuel Kaski
2013 Eurographics Conference on Visualization  
Dimensionality reduction for data visualization has recently been formulated as an information retrieval task with a well-defined objective function.  ...  The formulation was based on preserving similarity relationships defined by a metric in the input space, and explicitly revealed the need for a tradeoff between avoiding false neighbors and missing neighbors  ...  That is, we optimize the visualization for information retrieval under uncertainty of the user's preferred similarities.  ...
