I am using Train Vector Classifier to classify a layer using the libsvm one
class model made from the Train Vector Classifier in OTB. I am using OTB
6.6 with QGIS 3. On the Vector Classifier info page (here
<https://www.orfeo-toolbox.org/CookBook/Applications/app_VectorClassifier.html)>)
it says the libsvm model supports the confusion matrix output option but
when I run the tool, I get an error saying the confidence map is not
supported for that classifier. Anyone know how to fix this or have any
suggestions on a work around to run an accuracy assessment on my classified
layer (shapefile)? The layer I am trying to classify is the output from
LSMSVectorization step of the segmentation process. Thanks!

Katie
