transform example set to histogram
Is there a possibility to work on the histogram of the data (as can be shown by the plotter)?
- given an example set with several instances
- discretize values of one attribute in f bins
- return an example set with f attributes (corresponding to the f bins) which contains only one instance (values are instance counts of source example set)
I want to use this to get a representation of an example set and then compare the histogram against histograms of other example sets (e.g. by applying Euklidian or Manhattan distance measure to the histrogram vector).
There are operators like BinDiscretization and Aggregation, but is there another operator which performs exactly what can be shown by histogram plotter?
