An industrial microphone is installed on the shearer and the cutting sound is collected as the recognition criterion to overcome the disadvantages of giant size, contact measurement and low identification rate of traditional detectors. To avoid end-point effects and get rid of undesirable intrinsic mode function (IMF) components in the initial signal, IEEMD is conducted on the sound. The end-point continuation based on the practical storage data is performed first to overcome the end-point effect. Next the average correlation coefficient, which is calculated by the correlation of the first IMF with others, is introduced to select essential IMFs. Then the energy and standard deviation of the reminder IMFs are extracted as features and PNN is applied to classify the cutting patterns. Finally, a simulation example, with an accuracy of 92.67%, and an industrial application prove the efficiency and correctness of the proposed method.<\/jats:p>","DOI":"10.3390\/s151127721","type":"journal-article","created":{"date-parts":[[2015,11,2]],"date-time":"2015-11-02T02:53:57Z","timestamp":1446432837000},"page":"27721-27737","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["A Cutting Pattern Recognition Method for Shearers Based on Improved Ensemble Empirical Mode Decomposition and a Probabilistic Neural Network"],"prefix":"10.3390","volume":"15","author":[{"given":"Jing","family":"Xu","sequence":"first","affiliation":[{"name":"School of Mechatronic Engineering, China University of Mining & Technology, No. 1 Daxue Road, Xuzhou 221116, China"}]},{"given":"Zhongbin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering, China University of Mining & Technology, No. 1 Daxue Road, Xuzhou 221116, China"}]},{"given":"Chao","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering, China University of Mining & Technology, No. 1 Daxue Road, Xuzhou 221116, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4087-9430","authenticated-orcid":false,"given":"Lei","family":"Si","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering, China University of Mining & Technology, No. 1 Daxue Road, Xuzhou 221116, China"},{"name":"School of Information and Electrical Engineering, China University of Mining & Technology,  No. 1 Daxue Road, Xuzhou 221116, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8632-6532","authenticated-orcid":false,"given":"Xinhua","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering, China University of Mining & Technology, No. 1 Daxue Road, Xuzhou 221116, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,10,30]]},"reference":[{"key":"ref_1","unstructured":"Brady, B.H.G., and Brown, E.T.
