"Model Applier Bug causing incorrect interpretation of Labels (RapidMiner 4.4)"

wotsiznamiz

Hi - I've noticed a handful of related threads on this topic, but no great solutions that will work with the problem I'm facing...

I have used RapidMiner + WVTool to build a text-mining model.  When i use ModelApplier to apply that model to a new data set, it seems to somehow misinterpret my original labels.

After several failed attempts to get a correct validation of my model using Model Applier, I finally tested this out by building a model and then applying that same model to the *identical* data set sorted merely in a different order.  When I do this, it returns a file that has somehow flipped the values in the label field.  So clearly something is going wrong either with my code or with the ModelApplier Operator.

Here are some threads that sound related...

Hello wotsiznamiz

Since I do not have your files, I cannot rerun the process . Please take a look at this thread: http://rapid-i.com/rapidforum/index.php/topic,776.msg2897.html#new

Now try this:
Check the examplesets in the resulttab after both apply steps to see whether the sequence of possible values has changed for the label (Meta Data View). If this is true, than you were a victim of the same bug as in the mentioned thread. I hope the workaround is working for your problem, too.

kind regards,

Steffen

PS: Oh, and thanks for the flowers  ;D.
