In this study, a deep learning network based on various sensor data is proposed for identifying the roads where the vehicle is driving. Long-Short Term Memory (LSTM) unit and ensemble learning are utilized for network design and a feature selection technique is applied such that unnecessary sensor data could be excluded without a loss of performance. Real vehicle experiments were carried out for the learning and verification of the proposed deep learning structure. The classification performance was verified through four different test roads. The proposed network shows the classification accuracy of 94.6% in the test data.<\/jats:p>","DOI":"10.3390\/s18124342","type":"journal-article","created":{"date-parts":[[2018,12,10]],"date-time":"2018-12-10T03:36:41Z","timestamp":1544413001000},"page":"4342","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Road Surface Classification Using a Deep Ensemble Network with Sensor Feature Selection"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1186-7737","authenticated-orcid":false,"given":"Jongwon","family":"Park","sequence":"first","affiliation":[{"name":"Department of Automotive Engineering, Hanyang University, Seoul 04763, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8506-1077","authenticated-orcid":false,"given":"Kyushik","family":"Min","sequence":"additional","affiliation":[{"name":"Department of Automotive Engineering, Hanyang University, Seoul 04763, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0290-5121","authenticated-orcid":false,"given":"Hayoung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Automotive Engineering, Hanyang University, Seoul 04763, Korea"}]},{"given":"Woosung","family":"Lee","sequence":"additional","affiliation":[{"name":"Chassis System Control Development Team, Hyundai Motor Company, Gyeonggi-do 18280, Korea"}]},{"given":"Gaehwan","family":"Cho","sequence":"additional","affiliation":[{"name":"Autonomous Vehicle Technology Laboratory, SW Part, CTO, LG Electronics, Seoul 07796, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7179-7841","authenticated-orcid":false,"given":"Kunsoo","family":"Huh","sequence":"additional","affiliation":[{"name":"Department of Automotive Engineering, Hanyang University, Seoul 04763, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"24411","DOI":"10.1109\/ACCESS.2018.2830661","article-title":"A Survey of Deep Learning: Platforms, Applications and Emerging Research Trends","volume":"6","author":"Hatcher","year":"2018","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1080\/00423110500333840","article-title":"Road profile input estimation in vehicle dynamics simulation","volume":"44","author":"Imine","year":"2006","journal-title":"Veh.
