...Chi Yang; Korkut Kaynardag; Guan-Wei Lee; Salvatore Salamone This study presents an application of a long short-term memory autoencoder (LSTM AE) for the detection of broken rails based on laser Doppler vibrometer (LDV) measurements. This work is part of an ongoing project aimed at developing...

... is compressed using a deep autoencoder model. The compressed feature is used for hyperparameter tuning, training, and testing of several supervised ML algorithms, and their performance in the identification of debonding zone and prediction of its size is analyzed. Finally, the trained ML algorithms are tested...
