We propose an automatic weight redistribution ensemble model based on transfer learning (TL) for detecting leaks in diverse power plant environments, overcoming the challenges of site-specific AI methods. This innovative model processes time series acoustic data collected from multiple homogeneous sensors located at different positions into three-dimensional root-mean-square (RMS) and frequency volume features, enabling accurate leak detection. Utilizing a TL-driven, two-stage learning process, we first train residual-network-based models for each domain using these preprocessed features. Subsequently, these models are retrained in an ensemble for comprehensive leak detection across domains, with control weight ratios finely adjusted through a softmax score-based approach. The experiment results demonstrate that the proposed method effectively distinguishes low-level leaks and noise compared to existing techniques, even when the data available for model training are very limited.<\/jats:p>","DOI":"10.3390\/s24154999","type":"journal-article","created":{"date-parts":[[2024,8,2]],"date-time":"2024-08-02T09:34:17Z","timestamp":1722591257000},"page":"4999","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Automatic Weight Redistribution Ensemble Model Based on Transfer Learning to Use in Leak Detection for the Power Industry"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9623-0878","authenticated-orcid":false,"given":"Sungsoo","family":"Kwon","sequence":"first","affiliation":[{"name":"Department of AI and Big Data Engineering, Daegu Catholic University, 13-13, Hayang-ro, Hayang-eup, Gyeongsan-si 38430, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7093-3218","authenticated-orcid":false,"given":"Seoyoung","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of AI and Big Data Engineering, Daegu Catholic University, 13-13, Hayang-ro, Hayang-eup, Gyeongsan-si 38430, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9057-9201","authenticated-orcid":false,"given":"Tae-Jin","family":"Park","sequence":"additional","affiliation":[{"name":"Nuclear System Integrity Sensing & Diagnosis Division, Korea Atomic Energy Research Institute (KAERI), 62, Gwahak-ro, Yuseong-gu, Daejeon 34142, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0035-5261","authenticated-orcid":false,"given":"Ji-Hoon","family":"Bae","sequence":"additional","affiliation":[{"name":"Department of AI and Big Data Engineering, Daegu Catholic University, 13-13, Hayang-ro, Hayang-eup, Gyeongsan-si 38430, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"84","DOI":"10.1016\/j.partic.2020.07.005","article-title":"A leakage particle\u2013wall impingement based vibro-acoustic characterization of the leaked sand\u2013gas pipe flow","volume":"55","author":"Wang","year":"2021","journal-title":"Particuology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1219","DOI":"10.1177\/1475921719881979","article-title":"Leak detection on water pipelines in unsaturated ground by discrete fibre optic sensing","volume":"19","author":"Jacobsz","year":"2019","journal-title":"Struct.
