Structure-Based Similarity Search with Graph Histograms
Objects like road networks, CAD/CAM components, electrical or electronic circuits, molecules, can be represented as graphs, in many modern applications. In this paper, we propose ...

The P-Square Algorithm for Dynamic Calculation of Percentiles and Histograms without Storing Observations
A heuristic algorithm is proposed for dynamic calculation of the median and other quantiles. The estimates are produced dynamically as the observations are generated. The observati...
