It might be better introducing a bit more generic fix, like .close() method in an AbstractEventStream, so the resources the stream allocated during creation will be released explicitly upon .close() method call.

After training, temporary files like events37537375696294525.tmp remain in the temporary directory.
AFAIK, the problem
TwoPassDataIndexer -> open reader in the FileEventStream -> reader remains open -> file.delete() does not work.
A possible solution might be - remove deleteOnExit() due unreliabilty and memory consumption, add explicit .close() call:

Hi,
take a look at this thread:
https://sourceforge.net/projects/maxent/forums/forum/18385/topic/1925312
Also note that a feature with a value of "0" is ignored by the model.
Hope this helps...Tom.

I tried to learn how to use this package these days via run the examples firstly. Surprisingly, I found that the results of the examples are not right.
I do the testing using the training data, the testing results are very bad. I also tried my own data, which have an abvious difference among classes, and the results are also bad.
I am wondering if there's something wrong with the examples...

I have train a ME model using the data:
sim=1 chain=0 b
sim=1.1 chain=0.1 b
sim=1.0 chain=0.1 b
sim=1.1 chain=0 b
sim=0 chain=1 nb
sim=0.1 chain=1.1 nb
sim=0 chain=1.1 nb
sim=0.1 chain=1.0 nb
and then use the same data without "b" or "nb" to test, the results are:
For context: sim=1
b[0.9990] nb[0.0010]
For context: sim=1.1
b[0.9995]...

Hi,
The features you have will work as is with the RealValueFileEventStream. I would recommend however that you change your non-real-valued feature to a slightly different format. As they are the code will try and turn true and false into a float, generate an exception, catch that exception and treat them as binary features. With the "=" sign if won't try to make a float out of...

hi, Tom:
My event are like this: "time=2.5 sim=0.6 mus=true sil=false".
It seems I can not employ this event directly to train the model.
Do you mean that I can change this event into the form like "time=2.5 sim=0.6 mus", and if there is anotoher event with both 'mus' and 'sil' true, the event will be changed to be "time=2.5 sim=0.6 mus sil"?
Looking...

Hi, everybody.
According the introduction of maxent-2.5.2, it could process both binary and real data, via the option of -real.
but If I have both binary and real data in the same event, how could I use them? or do I have to transfer the binary data into real or the real data to binary?
Your answers will be greatly appreciated, thanks a lot.

Hi,
Yes they can. I'm not sure how you are creating your events but in RealValueFileEventStream binary events look like "name=1.2". Binary event don't have a value at the end. A binary event is just like a real-valued event with a value of 1.0.
Hope this helps...Tom.
