Dense retrieval is becoming one of the standard approaches for document and passage ranking. The dual-encoder architecture is widely adopted for scoring question-passage pairs due to its efficiency and high performance. Typically, dense retrieval models are evaluated on clean and curated datasets. However, when deployed in real-life applications, these models encounter noisy user-generated text. That said, the performance of state-of-the-art dense retrievers can substantially deteriorate when exposed to noisy text. In this work, we study the robustness of dense retrievers against typos in theResearch goal: What is the impact of training data diversity in WebFAQ on the robustness of dense retrievers against adversarial query perturbations in non-English XQuAD evaluations?Autonomous synthesis report generated by Assignee Research.
