In this paper, we present our methods to tackle the difficulties of the provided task. Experiments with our approaches on the competitive dataset from AICity Challenge 2021 show that our techniques achieve Mean Reciprocal Rank score of 0.1701 on the public test dataset and 0.1571 on the private test dataset.","url_abs":"https://openaccess.thecvf.com/content/CVPR2021W/AICity/html/Nguyen_Contrastive_Learning_for_Natural_Language-Based_Vehicle_Retrieval_CVPRW_2021_paper.html","url_pdf":"https://openaccess.thecvf.com/content/CVPR2021W/AICity/papers/Nguyen_Contrastive_Learning_for_Natural_Language-Based_Vehicle_Retrieval_CVPRW_2021_paper.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"contrastive-learning-for-natural-language","repo_url":"https://github.com/VietHoang1512/CVPR-track-5","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"pytorch","reach":null}],"tasks":[{"task_slug":"contrastive-learning","task_name":"Contrastive Learning"},{"task_slug":"retrieval","task_name":"Retrieval"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
