GClasses::SOM::SVG2DWeightReporter Class Reference

Detailed Description

Writes out sequentially numbered svg files giving the weight locations in 2 dimensions of input space connected by a mesh that connects each weight with its nearest neighbors. Writes one file each time newStatus is called and once when stop is called. The output of stop may duplicate the last newStatus's output, but is not guaranteed to.

Generated filenames will be of the form: base_d+.svg (where d+ means 1 or more decimal digits). If the training algorithm gives a good estimate of the number of iterations and sub-iterations, the number of digits in the name will be the same for all generated filenames. If the estimate is low, then the filename size may increase. If it does not give any estimate, more digits will be added at the 10 millionth filename. The digits will start counting at 1.
