FAQ / Re: Propagation of inconsistent evidence has been attempted

Hi Frans

It is a good question. Without having access to your model nor your data I can only give you a qualified guess.

What could have caused the error in your model is that somehow the learning algorithm encounters cases that are impossible according to the probabilities in the model.

Did you manually change the probabilities in the model prior to running the EM learner?
If so, that may be what causes your problems. For instance, in your model you may have A --> B and some state in A which has prior probability 0 or a state in B which has conditional probability 0 given some state in A.

I have been playing around with the EM-Learner and that was the only way I could generate the error message.

Please let us know if this could be a likely explanation.

have a good day!

If that was not clear from the above, "the dll" file would be the one you find in ...\Hugin Expert\Hugin Dist 7.8\HDE7.8J\Bin

Hi mbedward.

In eclipse you must add the dll file to the library path. Otherwise the java runtime environment will not be able to combine the JBC with the binary code.

In your eclipse project select Run As... -> Run Configurations -> Arguments and add the following in the field labeled "VM Arguments":
-Djava.library.path=Whereeveryourdllfileislocated

I hope this helps.

Regards
Nicolaj
