A Payload Optimization Method for Federated Recommender Systems
[article]
2021
pre-print
Preserved Fulltext
We introduce the payload optimization method for federated recommender systems (FRS). ...
The selection process was guided by a novel reward function suitable for FL systems. So far as we are aware, this is the first optimization method that seeks to address item dependent payloads. ...
The findings confirm that the proposed method consistently performed Figure 1 : The payload optimization method proposed in this study for federated recommender systems (FRS). ...
