However, the problem of low accuracy rate of the recognition model caused by improper selection of training set samples by random split has severely restricted the development of LIBS in meat detection. Sample set portioning based on the joint x\u2013y distance (SPXY) method was applied for dividing the meat spectra into a training set and a test set. Then, the five kinds of meat samples (shrimp, chicken, beef, scallop, and pig liver) were classified by the support vector machine (SVM). With the random split method, Kennard\u2013Stone method, and SPXY method, the recognition accuracies of the SVM model were 90.44%, 91.95%, and 94.35%, respectively. The multidimensional scaling method was used to visualize the results of the sample split for the interpretation of the classification. The results showed that the identification performance of the SPXY method combined with the SVM model was best, and the accuracy rates of shrimp, chicken, beef, scallop, and pig liver were 100.00%, 100.00%, 100.00%, 78.57%, and 92.00%, respectively. Moreover, to verify the broad adaptability of the SPXY method, the linear discriminant analysis model, the K-nearest neighbor model, and the ensemble learning model were applied as the meat species identification model. The results demonstrated that the accuracy rate of the classification model can be improved with the SPXY method. In light of the findings, the proposed sample portioning method can improve the accuracy rate of the recognition model using LIBS.<\/jats:p>","DOI":"10.1364\/ao.430980","type":"journal-article","created":{"date-parts":[[2021,6,10]],"date-time":"2021-06-10T20:00:39Z","timestamp":1623355239000},"page":"5826","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Meat species identification accuracy improvement using sample set portioning based on joint x\u2013y distance and laser-induced breakdown spectroscopy"],"prefix":"10.1364","volume":"60","author":[{"given":"Lianbo","family":"Guo","sequence":"first","affiliation":[{"name":"Jilin University of Architecture and Technology"},{"name":"Huazhong University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weinan","family":"Zheng","sequence":"additional","affiliation":[{"name":"Jilin University of Architecture and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Chen","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiliang","family":"Wang","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenlin","family":"Hu","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanwu","family":"Chu","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"285","published-online":{"date-parts":[[2021,7,6]]},"reference":[{"key":"ao-60-20-5826-R1","doi-asserted-by":"publisher","first-page":"744","DOI":"10.1016\/j.jfoodeng.2013.07.004","volume":"119","author":"Tian","year":"2013","journal-title":"J.
