Implementation for the PREPRec paper, accepted at Recsys 2024. Our method enables cross-domain, cross-user zero-shot transfer competitive with in-domain SOTA models.

Quick start: Install packages from requirements.txt. Then follow the instructions in data folder for getting dataset and preprocessing. Then create a res folder to hold trained models and logs of results, and see sample.sh for examples for running and evaluating models.

Code credits: Original code is based off this pytorch SASRec implementation, with code also taken/repurposed from here, here, here and here.
