We evaluate our approach on a variety\nof sequence classification tasks with disparate label spaces. We outperform\nstrong single and multi-task baselines and achieve a new state-of-the-art for\ntopic-based sentiment analysis.","url_abs":"http://arxiv.org/abs/1802.09913v2","url_pdf":"http://arxiv.org/pdf/1802.09913v2.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":"multi-task-learning-of-pairwise-sequence","repo_url":"https://github.com/coastalcph/mtl-disparate","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"tf","reach":null}],"tasks":[{"task_slug":"classification","task_name":"General Classification"},{"task_slug":"multi-task-learning","task_name":"Multi-Task Learning"},{"task_slug":"sentiment-analysis","task_name":"Sentiment Analysis"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1802.09913","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
