libffm-linear prediction

[Gediminas Žylius]

Hello,

I'm trying to use libffm-linear library. Here are my outputs:

libffm-linear>windows\ffm-train -s 2 -l 0 -k 10 -t 50 -r 0.01 --au
to-stop -p test_data.txt train_data.txt model
iter tr_logloss va_logloss
1 0.25510 0.25017
2 0.25129 0.24927
3 0.25070 0.24882
4 0.25041 0.24843
5 0.25020 0.24821
6 0.25005 0.24808
7 0.24990 0.24801
8 0.24977 0.24800
9 0.24968 0.24820
Auto-stop. Use model at 8th iteration.

libffm-linear>windows\ffm-predict test_data.txt model output_file
logloss = 0.34800

Why prediction logloss differs from validation logloss on same file?

Thanks for the bug report. We will fix it.
