M. Chen and A. Golan, What may visualization processes optimize?   IEEE Transactions on Visualization and Computer Graphics , accepted in Dec. 2015.  DOI

Keywords:  theory of visualization, information theory, cost-benefit analysis, process optimization, data processing inequality, levels of visualization.
Questions:   What is a common metric for measuring the cost-benefit of machine- and human-centric data intelligence workflows? What are the fundamental factors in designing a cost-effective data intelligence workflow featuring both machine- and human-centric processes? Is there a mathematical basis to suggest the merits of visualization and interaction in data intelligence?
