We offer a Markovian formulation of structured world models and outline the notion of multi-level hybrid world representations that support compositional structure. We then review and suggest possible discovery paradigms, spanning distillation, interaction-driven continual learning, and ensemble learning.<\/jats:p>","DOI":"10.1609\/aaai.v40i48.42138","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T07:53:20Z","timestamp":1773820400000},"page":"41020-41024","source":"Crossref","is-referenced-by-count":0,"title":["Discovering Hybrid World Representations with Co-Evolving Foundation Models"],"prefix":"10.1609","volume":"40","author":[{"given":"Jiajun","family":"Wu","sequence":"first","affiliation":[]},{"given":"Yunzhi","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Hong-Xing","family":"Yu","sequence":"additional","affiliation":[]},{"given":"Joy","family":"Hsu","sequence":"additional","affiliation":[]},{"given":"Jiayuan","family":"Mao","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2026,3,14]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/42138\/46099","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/42138\/46099","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T07:53:21Z","timestamp":1773820401000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/42138"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,14]]},"references-count":0,"journal-issue":{"issue":"48","published-online":{"date-parts":[[2026,3,17]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v40i48.42138","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,14]]}}}
