Much of the previous work has relied on modeling the natural order of the conversation, using distance based offsets as an approximation of time. In this work, we hypothesize that leveraging the wall-clock temporal difference between turns is crucial for finer-grained control of dialogue scenarios. We develop a novel approach that applies a {\\it time mask}, based on the wall-clock time difference, to the associated slot embeddings and empirically demonstrate that our proposed approach outperforms existing approaches that leverage distance offsets, on both an internal benchmark dataset as well as DSTC2.","url_abs":"https://arxiv.org/abs/1907.11315v1","url_pdf":"https://arxiv.org/pdf/1907.11315v1.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":[],"tasks":[{"task_slug":"spoken-dialogue-systems","task_name":"Spoken Dialogue Systems"},{"task_slug":"video-salient-object-detection","task_name":"Video Salient Object Detection"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/video-salient-object-detection-on-mcl","task":"Video Salient Object Detection","dataset":"MCL","model":"TIMP","rank_in_archive_order":6,"of":8,"metrics":{"AVERAGE MAE":"0.113","MAX E-MEASURE":"0.760","S-Measure":"0.642"},"uses_additional_data":true},{"leaderboard":"/sota/video-salient-object-detection-on-segtrack-v2","task":"Video Salient Object Detection","dataset":"SegTrack v2","model":"TIMP","rank_in_archive_order":6,"of":8,"metrics":{"AVERAGE MAE":"0.116","S-Measure":"0.644","max E-measure":"0.768"},"uses_additional_data":true}],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
