The discussion here will perhaps help: https://sourceforge.net/projects/tadm/forums/forum/473054/topic/1675097
Note that TADM isn't being actively supported as far as I am aware. I tried to updated it a couple years ago, ran into trouble with the latest versions of PetSC and TAO and ran out of time to do it. Having said that it still has better training for maxent models since it does LMVM and OpenNLP Maxent still (sadly) just does GIS. Been on my todo to change that situation for some time, but I never seem to find the time. :( Jason On Wed, Sep 21, 2011 at 12:03 PM, Robert <bobes...@centrum.cz> wrote: > > Hello, > I am quite new to maximum entropy and unfortunately, I'm fighting with > input > to TADM (tadm.sf.net) and to OpenNLP.
