Despite their utility, the static characteristic of KGs poses challenges in dynamically evolving information landscapes. This has catalyzed the development of temporal knowledge graphs (TKGs), which introduce a temporal layer to KGs, facilitating the representation of knowledge progression through time. This study zeroes in on the critical task of TKG extrapolation, which is vital for forecasting future occurrences and offering foresight into emerging situations across a variety of fields. Most contemporary approaches to TKG extrapolation are predicated on the symmetrical encoder\u2013decoder paradigm, wherein the processes of representation learning and reasoning are harmoniously intertwined. While the encoder often garners the most attention due to its role in capturing and encoding information, the pivotal role of the decoder, which is often overlooked, is essential for direct inference and the accurate projection of temporal dynamics. To this end, we present the Householder-transformation-based temporal knowledge graph extrapolation (HTKGE) method: a groundbreaking encoder\u2013decoder framework that reimagines the decoder\u2019s contribution to TKG extrapolation. Our approach spotlights an adaptive decoder propelled by Householder transformations, which engage dynamically with the temporal encoding from the encoder. This interaction fosters a nuanced comprehension of the TKG\u2019s temporal trajectory. Our empirical evaluations across four benchmark TKG datasets substantiate HTKGE\u2019s consistent efficacy in TKG extrapolation tasks.<\/jats:p>","DOI":"10.3390\/sym16091166","type":"journal-article","created":{"date-parts":[[2024,9,6]],"date-time":"2024-09-06T06:18:35Z","timestamp":1725603515000},"page":"1166","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unleashing the Power of Decoders: Temporal Knowledge Graph Extrapolation with Householder Transformation"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8746-3347","authenticated-orcid":false,"given":"Fuqiang","family":"Yang","sequence":"first","affiliation":[{"name":"School of Data and Computer Science, Shandong Women\u2019s University, Jinan 250300, China"}]},{"given":"Yue","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Shandong Youth University of Political Science, Jinan 250103, China"}]},{"given":"Xuechen","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Data and Computer Science, Shandong Women\u2019s University, Jinan 250300, China"}]},{"given":"Shengnan","family":"Pang","sequence":"additional","affiliation":[{"name":"School of Journalism and Communication, Tsinghua University, Beijing 100190, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bollacker, K.D., Evans, C., Paritosh, P., Sturge, T., and Taylor, J.
