We observe that this limitation primarily arises from their inability to effectively handle the pervasive artifacts in RS imagery. To address this, we introduce Earth-Adapter, the first PEFT method specifically designed for RS artifact mitigation. Earth-Adapter introduces a novel Frequency-Guided Mixture of Adapters (MoA) approach, structured around a ''divide and conquer\" strategy. It first utilizes Discrete Fourier Transformation (DFT) to \"divide\" features into distinct frequency components, thereby effectively isolating artifact-related information from semantic signals. Subsequently, to ''conquer\" these artifact, MoA independently optimizes features within different subspaces and dynamically assigns weights via a router to aggregate the refined representations. This enables adaptive refinement of the VFM\u2019s representation space to mitigate the impact of artifacts. This simple yet highly effective PEFT method demonstrably mitigates artifacts and significantly enhances VFMs performance on RS segmentation tasks. Extensive experiments demonstrate Earth-Adapter's effectiveness on in-domain semantic segmentation (SS), as well as Domain Adaptive (DA) and Domain Generalized (DG) semantic segmentation tasks. Compared with the baseline Rein, Earth-Adapter significantly improves mIoU by 1.2% in SS, 9.0% in DA, and 3.1% in DG benchmarks. Our code and weights will be released soon.<\/jats:p>","DOI":"10.1609\/aaai.v40i6.42498","type":"journal-article","created":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T23:16:32Z","timestamp":1773789392000},"page":"4941-4949","source":"Crossref","is-referenced-by-count":0,"title":["Earth-Adapter: Bridge the Geospatial Domain Gaps with a Frequency-Guided Mixture of Adapters"],"prefix":"10.1609","volume":"40","author":[{"given":"Xiaoxing","family":"Hu","sequence":"first","affiliation":[]},{"given":"Ziyang","family":"Gong","sequence":"additional","affiliation":[]},{"given":"Yupei","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Yuru","family":"Jia","sequence":"additional","affiliation":[]},{"given":"Fei","family":"Lin","sequence":"additional","affiliation":[]},{"given":"Dexiang","family":"Gao","sequence":"additional","affiliation":[]},{"given":"Ke","family":"An","sequence":"additional","affiliation":[]},{"given":"Jianhong","family":"Han","sequence":"additional","affiliation":[]},{"given":"Zhuoran","family":"Sun","sequence":"additional","affiliation":[]},{"given":"Gen","family":"Luo","sequence":"additional","affiliation":[]},{"given":"Xue","family":"Yang","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\/42498\/46459","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/42498\/46459","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T23:16:33Z","timestamp":1773789393000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/42498"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,14]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2026,3,17]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v40i6.42498","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]]}}}
