I am slightly confused. Is this a factorisation machine or a field-aware factorisation machine?
R.T.
How hard is to add AUC as a optimization function?
Now the only option is logloss.
Is there a need the feature IDs to be unique or is it enough the combination of field + feature ID to be unique?
For example
If we assume that field 1 is movie and field 2 is user and user A has ID 123 and movie B has ID 123
is this a valid row:
1:123:1 2:123:1
I found that there are several projects about ffm in your github, such as libffm-ftrl,Difacto_DMLC.Which one would you recommend to use? Do you have any data about their effectiveness and efficiency on benchmark dataset?
I'm using the data from real users to make click-through rate prediction.
training sample: 747265
testing sample: 261168
I got training AUC: 0.66824
testing AUC: 0.54578
It seems that the model is overfitting.
how should i finetune the hyper-parameters to avoid overfitting?
https://github.com/superclocks/ffm/blob/master/libffm-ftrl-1.13/ffm.cpp
ffm_long align0 = (ffm_long)model.k*3;
vs https://github.com/CNevd/libffm-ftrl/blob/master/ffm.cpp
_ffm_long align0 = (ffm_long)model.k*2;_
or maybe one is not right implemented?
thanks very much
