Add option in Merger to forget old counters "exponentially" as in online algorithms #13

Closed sashafrey closed 10 years ago

sashafrey commented 10 years ago

Currently Merger keeps accumulating counters. It never resets them to zero, an do not "exponentially decrease" values, corresponding to "old iterations". This is suboptimal since on the first steps Phi matrix was inacurate we accumulated some noise.

Common for online algorithms is to exponentially decrease counters. You are welcome to suggest an actual implementation details for this feature, and implement it :)

Update: as of today counters n_wt are reset after every outer iteration, but we still lack an option to exponentially decay n_wt weights.
