Large data sets comprising multiple correlating attributes may include phenomena hard to identify and understand using traditional data analysis and visualization methods. HeatMiner is a new visual data mining technology which visualizes the data as three-dimensional heatmaps. Even complex patterns missed by other methods are easy to recognize from 3D-heatmaps with a single glance. Go and try HeatMiner with your own data at the Cloud’N’Sci.fi Algorithms-as-a-Service marketplace!
