Modality-Aware Identity Construction and Counterfactual Structure Learning for ID-Free Multimodal Recommendation
MAIL constructs modality-aware ID-free identities via dynamic positional encoding modulation and applies counterfactual structure learning with popularity penalization, yielding 7.81% Recall@10 and 12.81% NDCG@10 gains on five Amazon datasets.
