Researchers have developed a new method called UnIte for unsupervised domain adaptation in information retrieval. This technique improves how neural retrievers generalize to new domains by strategically selecting documents for pseudo query generation. UnIte focuses on model uncertainty, filtering documents with high aleatoric uncertainty and prioritizing those with high epistemic uncertainty to maximize learning efficiency. Experiments showed significant improvements in nDCG@10 scores, particularly with smaller training sample sizes. AI
