The RMSE does not change even if I give no trust data to TrustSVD, TrustMf

Is this the correct behaviour? Here is my config file, empty is a directory with no files. The RMSE is just as good as the one for which I give the trust information.

data.appender.class=social
data.appender.path=empty

rec.recommender.class=trustsvd
rec.iterator.learnrate=0.005
rec.iterator.learnrate.maximum=-1
rec.iterator.maximum=30
rec.user.regularization=0.5
rec.item.regularization=0.5
rec.social.regularization=1.0
rec.bias.regularization=0.5
rec.factor.number=10
rec.learnrate.bolddriver=false
rec.learnrate.decay=1.0
rec.recommender.earlystop=false
rec.recommender.verbose=true
