Geology prediction based on operation data of TBM: comparison between deep neural network and statistical learning methods [PDF]
2019 1st International Conference on Industrial Artificial
Intelligence (IAI), 2018 Tunnel boring machine (TBM) is a complex engineering system widely used for tunnel construction. In view of the complicated construction environments, it is necessary to predict geology conditions prior to excavation. In recent years, massive operation data of TBM has been recorded, and mining these data can provide important references and useful ...
