Description: This function takes in a set of candidate users and ranks them for a who-to-follow
|
||||
request by sampling from the Placket-Luce distribution
|
||||
(https://cran.rstudio.com/web/packages/PlackettLuce/vignettes/Overview.html) with a three
|
||||
variations. The first variation is that the scores of the candidates are multiplied by
|
||||
multiplicativeFactor before sampling. The second variation is that the scores are
|
||||
exponentiated before sampling. The third variation is that depending on how many who-to-follow
|
||||
positions are being requested, the first k positions are reserved for the candidates with the
|
||||
highest scores (and they are sorted in decreasing order of score) and the remaining positions
|
||||
are sampled from a Placket-Luce. We use the efficient algorithm proposed in this blog
|
||||
https://medium.com/swlh/going-old-school-designing-algorithms-for-fast-weighted-sampling-in-production-c48fc1f40051
|
||||
to sample from a Plackett-Luce. Because of numerical stability reasons, before sampling from this
|
||||
distribution, (1) we subtract off the maximum score from all the scores and (2) if after
|
||||
this subtraction and multiplication by the multiplicative factor the resulting score is <= -10,
|
||||
we force the candidate's transformed score under the above algorithm to be 0 (so r^(1/w) = 0)
|
||||
where r is a random number and w is the transformed score.
|
||||
|
||||
inputs:
|
||||
- target: HasClientContext (WTF request)
|
||||
- candidates: sequence of CandidateUsers (users that need to be ranked from a who-to-follow
|
||||
request) each of which has a score
|
||||
|
||||
inputs accessed through feature switches, i.e. through target.params (see the following file:
|
||||
"follow-recommendations-service/common/src/main/scala/com/twitter/follow_recommendations/common/
|
||||
transforms/weighted_sampling/SamplingTransformParams.scala"):
|
||||
- topKFixed: the first k positions of the who-to-follow ranking correspond to the users with the k
|
||||
highest scores and are not sampled from the Placket-Luce distribution
|
||||
- multiplicativeFactor: multiplicativeFactor is used to transform the scores of each candidate by
|
||||
multiplying that user's score by multiplicativeFactor
|
||||
|
||||
output:
|
||||
- Sequence of CandidateUser whose order represents the ranking of users in a who-to-follow request
|
||||
This ranking is sampled from a Placket-Luce distribution.
