vowpalwabbit - Vowpal Wabbit: obtaining a readable_model when in --daemon mode -

i trying stream data vw in --daemon mode, , obtain @ end value of coefficients each variable. therefore i'd vw in --daemon mode either: - send me current value of coefficients each line of data send. - write resulting model in "--readable_model" format.

i know dummy example trick save_namemodel | ... vw in daemon mode save model given file, isn't enough can't access coefficient values file.

any idea on how solve problem ?

unfortunately, on-demand saving of readable models isn't supported in code shouldn't hard add. open source software there users improve according needs. may open issue on github, or better, contribute change.

see: this code line binary regressor saved using save_predictor(). 1 envision "rsave" or "saver" tag/command store regressor in readable form being done in code line

as work-around may call vw --audit , parse every audit line feature names , current weights would:

• make vw slower
• require parsing every line values rather on demand
