A new research paper introduces SwapRec, a method designed to improve the accuracy of recommender systems when dealing with "cold items" – items that have few or no interactions. The approach involves applying the same item-swapping heuristics used at inference time to the training process itself. Experiments on sequential models across online shopping, movie, and music domains demonstrated that SwapRec significantly enhances recommendation accuracy and increases the proportion of cold items presented to users, regardless of the underlying sequential architecture.
