I am loading a model saved in a model file and applying it to a textinput. After the model applier, I have a performance operator.
The Performance operator (and other related operators like BinomialClassificationPerformance and ClassificationPerformance) gives a Nullpointer exception. The problem does not seem to be with my corpus. I am also adding the appropriate output word list.
Please post the complete process here ... otherwise it is too painful to reconstruct the error. Best you post a repeatable process by using a datagenerator-operator instead of your own input. This would be very helpful.
Hi, without any further information I cannot say anything about this. If you could post the process and exchange the data source by a data generation operator, then I would be able to trace the problem down.
Details of the problem. Please address my problem..

The input directories:

Perhaps the audience does not love them as much.
Note: I tried working with the actual dataset (which is much larger in size) too. But I get the same error.
As I see it, the class labels are generated but the numbers cannot be produced.
Seems like there is a bug in the code or (more probably) an invalid input has not been caught (and there are a lot of invalid inputs...). Without your files (data and model) we will not be able to track down the problem. If you are not able to share the data (e.g. because it is confidential), then replace the real data with some generated via an operator from Utility->Data Generation. Otherwise we are restricted to guessing, and seriously, we all have simply too much to do to provide this amount of support.
beside: 1. Is "TextInput" an officially released operator ? If this is true, where can I find it ? 2. Do you use rapidminer 4.6 or rapidminer 5 ?
Here is another idea: Please write the output of modelapplier to a file (e.g. using examplesetwriter or csvwriter), but only the special ones (i.e. all non-regular fields). This way you wont see any confidential data.
upload the data to a place of your choice and post the link here. If this is not possible for any reason, send the file to my email address.
edit: please use examplesetwriter ...otherwise the metadata is lost. edit2: what do you mean above with "numbers cannot be produced" ? Does that mean that the confidence attribute is all unknown ? In this case you do not have to post data. In this case it would be more interesting to see your model building process (the process, which generated the *.mod-file).
