In sedimentary settings, it is difficult for a single geological classification process to comprehensively express the complex geological spatio-temporal relationships of underground space. In response to this problem, we proposed a progressive geological modeling strategy to reconstruct the subsurface based on a machine learning approach. The modeling work consisted of two-stage classifications. In the first stage, a stratigraphic classifier was built by mapping spatial coordinates into stratigraphic classes, which reflected the geological time information of the geological unit. Then, the obtained stratigraphic class was used as a new feature for the training of the lithologic classifier in the second stage, which allowed the stratigraphic information to be implicitly converted into a new rule condition and enabled us to output the lithologic class with stratigraphic implications. Finally, the joint Shannon entropy of two classifications was calculated to evaluate the uncertainty of the total steps. The experiment built a fine-grained 3D geological model with integrated expression of stratigraphic and lithologic information and validated the effectiveness of the strategy. Moreover, compared with the conventionally trained classifier, the misclassification of the lithologic class between different strata in the progressive classification results has been reduced, with the improvement of the F1-score from 0.75 to 0.78.<\/jats:p>","DOI":"10.3390\/ijgi12030097","type":"journal-article","created":{"date-parts":[[2023,2,27]],"date-time":"2023-02-27T04:13:16Z","timestamp":1677471196000},"page":"97","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Progressive Geological Modeling and Uncertainty Analysis Using Machine Learning"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3350-1939","authenticated-orcid":false,"given":"Hong","family":"Li","sequence":"first","affiliation":[{"name":"School of Geography and Information Engineering, China University of Geosciences, Wuhan 430078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2387-5419","authenticated-orcid":false,"given":"Bo","family":"Wan","sequence":"additional","affiliation":[{"name":"School of Computer Science, China University of Geosciences, Wuhan 430078, China"},{"name":"National Engineering Research of Geographic Information System, Wuhan 430074, China"}]},{"given":"Deping","family":"Chu","sequence":"additional","affiliation":[{"name":"School of Geography and Information Engineering, China University of Geosciences, Wuhan 430078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5570-6391","authenticated-orcid":false,"given":"Run","family":"Wang","sequence":"additional","affiliation":[{"name":"Geological Environmental Center of Hubei Province, Wuhan 430034, China"}]},{"given":"Guoxi","family":"Ma","sequence":"additional","affiliation":[{"name":"Wuhan Zondy Cyber Science & Technology Co., Ltd., Wuhan 430073, China"}]},{"given":"Jinming","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Computer Science, China University of Geosciences, Wuhan 430078, China"}]},{"given":"Zhuocheng","family":"Xiao","sequence":"additional","affiliation":[{"name":"National Engineering Research of Geographic Information System, Wuhan 430074, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/bs.agph.2018.09.001","article-title":"3-D structural geological models: Concepts, methods, and uncertainties","volume":"59","author":"Wellmann","year":"2018","journal-title":"Adv.
