Mitigating Negative Transfer in Multi‑Target Cross‑Domain Recommendation with Unbiased Information Extraction and Adaptation (UIEA)

The paper, accepted at AAAI 2025, proposes UIEA—a three‑stage method that addresses data imbalance and negative transfer in multi‑target cross‑domain recommendation by extracting unbiased shared representations and adapting them with a user‑item attention module, achieving significant gains on Amazon, Douban, and IE datasets.
