The work is built on a farm IoT system that remotely monitors and tracks the state of cattle. A digital twin model of cattle based on Deep Learning (DL) is generated using the sensor data acquired from the farm IoT system. The physiological cycle of cattle can be monitored in real time, and the state of the next physiological cycle of cattle can be anticipated using this model. The basis of this work is the vast amount of data that is required to validate the legitimacy of the digital twins model. In terms of behavioural state, this digital twin model has high accuracy, and the loss error of training reach about 0.580 and the loss error of predicting the next behaviour state of cattle is about 5.197 after optimization. The digital twins model developed in this work can be used to forecast the cattle\u2019s future time budget.<\/jats:p>","DOI":"10.3390\/s22197118","type":"journal-article","created":{"date-parts":[[2022,9,21]],"date-time":"2022-09-21T00:08:09Z","timestamp":1663718889000},"page":"7118","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["AI Based Digital Twin Model for Cattle Caring"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3294-0131","authenticated-orcid":false,"given":"Xue","family":"Han","sequence":"first","affiliation":[{"name":"Centre of IoT and Telecommunication (CIoTT), School of Electrical and Information Engineering, Faculty of Engineering, University of Sydney, Camperdown, NSW 2006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zihuai","family":"Lin","sequence":"additional","affiliation":[{"name":"Centre of IoT and Telecommunication (CIoTT), School of Electrical and Information Engineering, Faculty of Engineering, University of Sydney, Camperdown, NSW 2006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7644-2046","authenticated-orcid":false,"given":"Cameron","family":"Clark","sequence":"additional","affiliation":[{"name":"Livestock Production and Welfare Group, School of Life and Environmental Sciences, Faculty of Science, University of Sydney, Camden, NSW 2570, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Branka","family":"Vucetic","sequence":"additional","affiliation":[{"name":"Centre of IoT and Telecommunication (CIoTT), School of Electrical and Information Engineering, Faculty of Engineering, University of Sydney, Camperdown, NSW 2006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6417-5788","authenticated-orcid":false,"given":"Sabrina","family":"Lomax","sequence":"additional","affiliation":[{"name":"Livestock Production and Welfare Group, School of Life and Environmental Sciences, Faculty of Science, University of Sydney, Camden, NSW 2570, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1016\/j.mfglet.2018.02.006","article-title":"Digital twin\u2013proof of concept","volume":"15","author":"Haag","year":"2018","journal-title":"Manuf.
