- Abstract
- Bayesian personalized ranking (BPR) is one of the state-of-the-art models for implicit feedback. Unfortunately, BPR has an limitation that it considers only the binary form of implicit feedback. In this paper, in order to overcome the limitation, we suggest an adapted version of BPR regarding the numeric value of implicit feedback like count data. Furthermore, we implement our model and original BPR in R and compare the results. This model may be useful to reflect implicit feedback more intensively than BPR.
