Re: [GRASS-user] Problem with v.class.mIR
[Guisseppe sent me the files]. The issue is your training file. As the manual page states: "The user provides a set of objects (or segments) to be classified, including all feature variables describing these object, and a set of objects to be used as training data, including the same feature variables as those describing the unknown objects, plus one additional column indicating the class each training falls into. The training data can, but does not have to be, a subset of the set of objects to be classified." IOW, the training data file has to contain the same feature variables as the data you wish to classify. Your data is: $ head -1 segmentation_map.csv cat,area,perimeter,compact_circle,fd $ head -1 training_map.csv cat,id,cate i.e. you training data only includes the id and the class, but not the variables describing the objects. The reason this is organised in this manner is that you might have training data which is independent of the data you wish to classify, i.e. the ids of the training data might not be linked to the ids in the object data. Another issue is that in your command, you do not provide a good name for the column that contains the actual class label in the training data: v.class.mlR segments_map=gbbb@PERMANENT training_map=tainning@PERMANENT train_class_column=fd [...] v.class.mlR segments_map=gbbb training_map=tainning train_class_column=class [...] Your training data does not contain a column 'fd' nor a column 'class'. I suppose that in your data it is the column 'cate'. Moritz On 4/12/19 10:38, Moritz Lennert wrote: Sorry for ignoring you up to now, just to much on the platter right now.
