getInputDescription
Maven
Hello RapidMiner Team
I am currently using rm4.6. I am not sure whether this is a bug or not, but if so and you have already fixed it in 5.0 I will remain silent and go back to my cave
.
I am talking about the function: getInputDescription(Class cls), especially in the case of BinominalClassificationPerformance aka AbstractPerformanceEvaluator . If I did understand this method it checks whether an ExampleSet (in the mentioned special case) is in the "input-area" and if this is true, it creates the parameter "keep_example_set".
So ... if I create a new process and add BinominalClassifcationPerformance, no parameter is shown. Accepted. However, adding more operators ...
Before I got problems with the usage of XVPrediction. In detail, the following situations occur, but I havent see a pattern yet (yes, I changed the process, no, as far as I remember, I did not change the critical part):
kind regards,
Steffen
PS: If I find a pattern, I will report it. But maybe this issue is already fixed in 5.0.

does not change what I see. Is this a bug ?

- keep_example_set is shown
- keep_example_set is not shown and the process crashes because the exampleset is missing
- keep_example_set is not shown, the validation-check is d'accord and the process run smoothly

you can't really say, it is fixed. I'd rather say: It has been removed completely. Thanks to the explicit dataflow and the ports, this method and it's strange behavior could be removed completely.
So I hope your cave is heated at least

and thanks for the reply. I admit I did not try out RM5.0 yet due to missing time, but I am running out of apologies.
I always prefer to use the community edition for self-building, but I am not able to build rm5.0-beta. I added another thread to keep the forum organization clean (here).
kind regards,
Steffen
