Checking the weights of the model

[piotrpiekos]

Hi,

how can i lookup the weights of the variables of FM after training?

[chihming]

did you save the model in a file?

[piotrpiekos]

is it possible to save the model from linux console? 2018-08-20 16:12 GMT+02:00 Chih-Ming Chen <notifications@github.com>:

[chihming]

for sgd and als mode, you can use -save_model to save the model parameters

[piotrpiekos]

thanks! Btw. am I using some obsolete documentation? Because I didn't find anything about that in libfm manual

[chihming]

this is a later added function, and I guess this is the only one not mentioned in the documentation

[piotrpiekos]

Okay, Thanks again for your help! pon., 20 sie 2018, 16:35 użytkownik Chih-Ming Chen <notifications@github.com> napisał:

For me load/save model doesnt work:

I've built libFM.exe on cygwin, but save_model/load_model doesn't seem to work:

$ ./libFM.exe -task r -method als -train data.libfm1 -test test.libfm1 -iter 100 -dim ‘5,5,10’ -load_model mod -save_model mod -out res.txt

Writing FM model to mod

File mod is in place and contains some numbers (mostly zeros).
Now I try to launch it again hoping that it will resume, but it starts from beginning:

$ ./libFM.exe -task r -method als -train data.libfm1 -test test.libfm1 -iter 100 -dim ‘5,5,10’ -load_model mod -save_model mod -out res.txt

Writing FM model to mod

I tried two repositories from github, both of them don't work as I expect. What am I missing?
