In order to address challenges such as the large computational workload, tedious training process, and multiple influencing factors associated with predicting earthquake casualties, this study proposes a Support Vector Machine (SVM) model utilizing Principal Component Analysis (PCA) and Bayesian Optimization (BO). The original data are first subjected to dimensionality reduction using PCA, with principal components contributing cumulatively to over 80% selected as input variables for the SVM model, while earthquake casualties are designated as the output variable. Subsequently, the optimal hyperparameters for the SVM model are obtained using the Bayesian Optimization algorithm. This approach results in the development of an earthquake casualty prediction model based on PCA-BO-SVM. Experimental results indicate that compared to the GA-SVM model, the BO-SVM model, and the PCA-GA-SVM model, the PCA-BO-SVM model exhibits a reduction in average error rates by 12.86%, 9.01%, and 2%, respectively, along with improvements in average accuracy and operational efficiency by 10.1%, 7.05%, and 0.325% and 25.5%, 18.4%, and 19.2%, respectively. These findings demonstrate that the proposed PCA-BO-SVM model can effectively and scientifically predict earthquake casualties, showcasing strong generalization capabilities and high predictive accuracy.<\/jats:p>","DOI":"10.3390\/systems13010024","type":"journal-article","created":{"date-parts":[[2025,1,2]],"date-time":"2025-01-02T07:44:53Z","timestamp":1735803893000},"page":"24","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Predicting Earthquake Casualties and Emergency Supplies Needs Based on PCA-BO-SVM"],"prefix":"10.3390","volume":"13","author":[{"given":"Fuyu","family":"Wang","sequence":"first","affiliation":[{"name":"School of Management Science and Engineering, Anhui University of Technology, Ma\u2019anshan 243032, China"},{"name":"Key Laboratory of Multidisciplinary Management and Control of Complex Systems of Anhui Higher Education Institutes, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"given":"Huiying","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Management Science and Engineering, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"given":"Huifen","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Management Science and Engineering, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"given":"Yan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Management Science and Engineering, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"given":"Yibo","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Management Science and Engineering, Anhui University of Technology, Ma\u2019anshan 243032, China"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104287","DOI":"10.1016\/j.ijdrr.2024.104287","article-title":"An AI-based framework for earthquake relief demand forecasting: Acase study in T\u00fcrkiye","volume":"102","author":"Biswas","year":"2024","journal-title":"Int.
