This repo contains the datasets for "Don't Waste It: Guiding Generative Recommenders with Structured Human Priors via Multi-head Decoding" (arXiv: https://arxiv.org/abs/2511.10492).

release-dataset.zip contains the user-item interactions, while release-information.zip contains the details of each item. We have a total of three datasets: Pixel8M.parquet, merrec_2000.parquet, eb_nerd_512.parquet. They are derived from PixelRec (https://epubs.siam.org/doi/pdf/10.1137/1.9781611978032.49), MerRec (https://doi.org/10.1145/3690624.3709394), and EB-NeRD (https://dl.acm.org/doi/abs/10.1145/3687151.3687152). We cleaned the Pixel8M dataset by relabeling some of the items belonging to the default "miscellaneous" tag. For MerRec and EB-NeRD, we removed all users with fewer than 2000 and 512 interactions, respectively.
