I'm having a struggle with SVM classification in QGIS OrfeoToolbox.
I used to work with RandomForest in R, but now I'm trying to figure out how the SVM algorithm works. I guess there would also be similarity between those packages(another topic).
Because I've no scripts nor knowledge about "e1071-SVM-Kernel" package, I've found a plugin within OrfeoToolbox; it simply requires a shapefile(polygons with values) and .xml file which includes every values for polygons in each bands.
My workflow was; Creating Polygons with mean & sd values for each band I used in. which was numbered over 30k. Then I've exported that shapefile into .xml like OGR plugin required from me.
Problem started in this point; Whenever I try to compute and right after train a model for final prediction, plugin doesn't produce any output even if I've executed it smoothly.
the modules I've used in a row are; 1.ComputeOGRLayersFeaturesStatistics 2.TrainOGRLayersClassifier 3.OGRLayerClassifier
- step doesn't work just because I've got no model from step 2, even if I define the output into a file.
What would be the problem? I hope I've set the problem clearly.
P.S. there's no warning nor error in the process when I execute it. There's nothing wrong with module Log. P.SS I'm using QGIS 2.14.7 with all the modules in it.
