There are services that recommend items such as shops or products to users based on scores or ratings that other users have given to those items.
Application of the Bradley-Terry(BT) model is widely considered as a way to achieve the statistical representation of items based on ratings that
users have given to items. The BT model evaluates the true preference parameters of items through the statistical representation. In this paper, a
divide and conquer optimization algorithm that enables estimating preference parameters in a feasible computational time when the number of items
scales up to the order of ten-thousands is proposed. A number of experimental studies using both synthetic and real datasets are provided to demonstrate
the effectiveness of this method. |
