Hello again,

I am again asking to community for help, as my wisdom has come to and end here. Here is a short descriptoion of what the code should do:
read input --> preprocessing + data preparation --> loop over combination of 2 of attributes --> Build and evaluate Decision tree for all combinations --> Write Attributes and Feature names to log and then to csv

But unfortunately is is stopping after some time, crashing the whole programm. I dont know if i make an error in der workflow or maybe it is using too much memory. Well, maybe some of you guys can give mie a tips.

    I just want to add, that it freezes the Process timer, for very long times. So maybe it is just using so much memory, that there is rarley any left for the programm itself. Is there anyoption to use only 90% of the available memory to keep something for the programm itself?

    Cheers,
    Markus

    Hi Markus,
    this is not possible, otherwise we would have done so long time ago :) I think you will need either more memory or test if there's some problem with the tree itself.
    By the way: You are generating a tree_depth macro, but do not use it for the  tree construction...

    Hey Sebastian,

    you are right. Treedepth was is not needed, as it is always 2 attributes. I think it is a bad idea to write/store the log at every iteration right? Would free memory help as it deletes all models and views?
    How do I get the log updated within the loop and written only after the iteration is finished?
    Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC overhead limit exceeded
    Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException
    Overall this message does not sound to good. This message appears not from the beginning, but after some time, most likely when the Process timer completely freezes.

    Cheers,
    Markus

    Hi Markus,
    indeed this message does not sound good. But as far as I saw, your attributes are numerical, aren't they? That's important, because the tree can use numerical attributes for multiple splits. Thus the depth can be in worst case equal to number of examples and this would definitively result in an out of memory exception...

    The free memory operator will not free anything that would not have been freed before java throws an out of memory exception.

    Dear Sebastian,

    Yes my attributes are numerical. To avoid a tree putting just one example into one split, I intent to use the minumum exaples per split feature and I set the maximum treedepth lower.
    I tried to modifiy the workflow by writing the log not to the hard drive but to the memory, but it did not change much. Here is my version I am working with  at the moment.

    I also tried to run it with a lower number of attributes (like 100 random by "Generate data") and it seems to work there. If someone experienced could help me please, I just dont know here the mistake is.

    Hi Markus,

    I think your code choked the cat because it kept storing extra copies of the log in memory. Here is code that selects all attribute pairs and logs their classification performance, hope that is what you had in mind.

    Thank you for your workflow!

    So using a cross-validation (X-Val) I would connect Performance Evaluation with the average output of the validation, and then the output of the X-Validation with the log operator, right?

    But how do I get the log written to a file (as data or even better example file) without this being done every single step?

    I agree, that writing a copy of the log file every iteration is killing the process. But i would still need the result of this search saved somewhere.

    Cheers,
    Markus
