Stars: 65

NineRec is a benchmark dataset suite for evaluating transferable recommendation models. It provides datasets for pre-training and transfer learning in recommender systems, focusing on multimodal and foundation model tasks. The dataset includes user-item interactions, item texts in multiple languages, item URLs, and raw images. Researchers can use NineRec to develop more effective and efficient methods for pre-training recommendation models beyond end-to-end training. The dataset is accompanied by code for dataset preparation, training, and testing in PyTorch environment.

In this paper, we evaluate the TransRec model based on end-to-end training of the recommender backbone and item modality encoder, which is computationally expensive. The reason we do this is because so far there is no widely accepted paradigm for pre-training recommendation models. End-to-end training shows better performance than pre-extracted multimodal features. However, we hope that NineRec can inspire more effective and efficient methods of pre-training recommendation models, rather than just limiting it to the end-to-end training paradigm. If one can develop a very efficient method that goes beyond end-to-end training but can be effectively transferable, it will be a great contribution to the community!!!
