RetrievalFormer: Dual-Encoder Transformer for Cold-Item Recommendation

Researchers have developed RetrievalFormer, a dual-encoder Transformer model designed for efficient approximate nearest neighbor retrieval and cold-item recommendation. This model addresses the challenge of incorporating new items into search and recommendation indexes without requiring retraining, a common issue with ID-softmax recommenders. RetrievalFormer maintains an open index by scoring new items based on features alone, achieving competitive performance on datasets like MovieLens-1M and MIND, particularly in cold-start scenarios. AI

IMPACT Introduces a novel approach to handling cold-start items in recommendation systems, potentially improving user experience and index efficiency.
