In many real-world applications, however, data of new categories arrive continuously, which requires the model has good extensibility. That is the model should be updated to accommodate data of new categories but still retain good performance for the old categories with minimum computation cost. Unfortunately, existing CMH methods fail to satisfy the extensibility requirements. In this work, we propose a novel extensible cross-modal hashing (ECMH) to enable highly efficient and low-cost model extension. Our proposed ECMH has several desired features: 1) it has good forward compatibility, so there is no need to update old hash codes; 2) the ECMH model is extended to support new data categories using only new data by a well-designed ``weak constraint incremental learning'' algorithm, which saves up to 91\\% time cost comparing with retraining the model with both new and old data; 3) the extended model achieves high precision and recall on both old and new tasks. Our extensive experiments show the effectiveness of our design.<\/jats:p>","DOI":"10.24963\/ijcai.2019\/292","type":"proceedings-article","created":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T03:46:05Z","timestamp":1564285565000},"page":"2109-2115","source":"Crossref","is-referenced-by-count":11,"title":["Extensible Cross-Modal Hashing"],"prefix":"10.24963","author":[{"given":"Tian-yi","family":"Chen","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, University of Science and Technology of China, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, University of Science and Technology of China, China"},{"name":"School of Data Science, University of Science and Technology of China, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shi-cong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, University of Science and Technology of China, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zi-long","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Northeastern University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bai-chuan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Physics, University of California Berkeley, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"name":"Twenty-Eighth International Joint Conference on Artificial Intelligence {IJCAI-19}","theme":"Artificial Intelligence","location":"Macao, China","acronym":"IJCAI-2019","number":"28","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2019,8,10]]},"end":{"date-parts":[[2019,8,16]]}},"container-title":["Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T03:48:18Z","timestamp":1564285698000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2019\/292"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2019,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2019\/292","relation":{},"subject":[],"published":{"date-parts":[[2019,8]]}}}
