Dear experts, I noticed for several settings of my system, I obtained optimal weights which are negative even though the default search range is [0, 0.5]. E.g. the weight for PhraseModel_4 (lexical feature) below. PhraseModel_1 0.045 PhraseModel_2 0.237 PhraseModel_3 0.048 PhraseModel_4 -0.097 PhraseModel_5 0.024
I was wondering if this is a normal behavior, and hope someone could enlighten me on that. If it is normal, how should I strictly enforce the range? Regards, Thang -- Luong Minh Thang WING group, School of Computing, National University of Singapore http://wing.comp.nus.edu.sg/~lmthang
