To address the poor fitting performance of single deep learning models on oil price data, which hampers accurate gasoline price prediction, this paper proposes a gasoline price prediction method based on a combined xLSTM\u2013XGBoost model. Using gasoline price data from June 2000 to November 2024 in Sichuan Province as a sample, the data are decomposed via STL decomposition to extract trend, residual, and seasonal components. The xLSTM model is then employed to predict the trend and seasonal components, while XGBoost predicts the residual component. Finally, the predictions from both models are combined to produce the final forecast. The experimental results demonstrate that the proposed xLSTM\u2013XGBoost model reduces the MAE by 14.8% compared to the second-best sLSTM\u2013XGBoost model and by 83% compared to the traditional LSTM model, significantly enhancing prediction accuracy.<\/jats:p>","DOI":"10.3390\/computers14070256","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T10:03:48Z","timestamp":1751277828000},"page":"256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["An xLSTM\u2013XGBoost Ensemble Model for Forecasting Non-Stationary and Highly Volatile Gasoline Price"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6990-6701","authenticated-orcid":false,"given":"Fujiang","family":"Yuan","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Taiyuan Normal University, Jinzhong 030619, China"},{"name":"Shanxi Key Laboratory of Intelligent Optimization Computing and Blockchain Technology, Jinzhong 030619, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xia","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chongqing University of Technology, Chongqing 400054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chongqing University of Technology, Chongqing 400054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chongqing University of Technology, Chongqing 400054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zihao","family":"Zuo","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chongqing University of Technology, Chongqing 400054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lusheng","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chongqing University of Technology, Chongqing 400054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4096-757X","authenticated-orcid":false,"given":"Yuxin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Energy and Power, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3995-3007","authenticated-orcid":false,"given":"Shaojie","family":"Gu","sequence":"additional","affiliation":[{"name":"Magnesium Research Center, Kumamoto University, Kumamoto 860-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2162-3798","authenticated-orcid":false,"given":"Yanhong","family":"Peng","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chongqing University of Technology, Chongqing 400054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"108233","DOI":"10.1016\/j.eneco.2025.108233","article-title":"Macroeconomic and sectoral effects of natural gas price: Policy insights from a macroeconometric model","volume":"143","author":"Hasanov","year":"2025","journal-title":"Energy Econ."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"482","DOI":"10.1631\/bdm.2400152","article-title":"Machine learning-enhanced soft robotic system inspired by rectal functions to investigate fecal incontinence","volume":"8","author":"Mao","year":"2025","journal-title":"Bio-Des.
