To realize the rational use of debris flow sample resources and improve the modeling efficiency, a unified model based on transfer learning was established for cross-regional DFSM. First, samples with 10 features collected from two debris flow-prone areas were separately used to perform factor prediction ability analysis (FPAA) based on the information gain ratio (IGR) method and then develop traditional machine learning models based on random forests (RF). Secondly, two feature matrices representing different areas were projected into a common latent feature space to obtain two new feature matrices. Then, the samples with new features were used together for FPAA and developing a unified machine learning model. Finally, the performance of the models was obtained and compared based on the area under curves (AUC) and some statistical results. All the conditioning factors played different roles in debris flow prediction in the two study areas, based on which two traditional models and a unified model were established. The unified model based on feature transferring realized efficient cross-regional modeling, solved the unconvincing problem of limited sample modeling, and enabled more accurate identification of some debris flow samples.<\/jats:p>","DOI":"10.3390\/rs14194829","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T03:30:37Z","timestamp":1664335837000},"page":"4829","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Research on Cross-Regional Debris Flow Susceptibility Mapping Based on Transfer Learning"],"prefix":"10.3390","volume":"14","author":[{"given":"Ruiyuan","family":"Gao","sequence":"first","affiliation":[{"name":"College of Construction Engineering, Jilin University, Changchun 130012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9143-225X","authenticated-orcid":false,"given":"Changming","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Construction Engineering, Jilin University, Changchun 130012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7775-3084","authenticated-orcid":false,"given":"Songling","family":"Han","sequence":"additional","affiliation":[{"name":"College of Construction Engineering, Jilin University, Changchun 130012, China"}]},{"given":"Hailiang","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Construction Engineering, Jilin University, Changchun 130012, China"}]},{"given":"Xiaoyang","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Construction Engineering, Jilin University, Changchun 130012, China"}]},{"given":"Di","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Construction Engineering, Jilin University, Changchun 130012, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Huang, H., Wang, Y., Li, Y., Zhou, Y., and Zeng, Z.
