“…In particular, thanks to advancements in machine learning algorithms (MLAs), the automatic diagnosis has made considerable progress in IMFD (Filippetti et al, 2000;Siddique et al, 2003;Choudhary et al, 2019;Liu et al, 2018;Esakimuthu Pandarakone et al, 2019;Ali et al, 2019;Martin-Diaz et al, 2018). The most widely used MLAs in IMFD are the following: support vector machines (SVMs) (Konar and Chattopadhyay, 2011;Widodo and Yang, 2007;Esakimuthu Pandarakone et al, 2019;Ali et al, 2019;Martin-Diaz et al, 2018), adaptive neural fuzzy inference system (ANFIS) (Ballal et al, 2007), fuzzy logic (Rodríguez et al, 2008), artificial neural networks (ANNs) (Bouzid et al, 2008;Esakimuthu Pandarakone et al, 2019;Glowacz and Glowacz, 2017;Martin-Diaz et al, 2018), genetic algorithms (Razik, de Rossiter Correa and Da Silva, 2009), extreme learning machine (ELM) (Coelho et al, 2014) and K-nearest neighbors (KNN) (Ali et al, 2019;Esakimuthu Pandarakone et al, 2019;Glowacz and Glowacz, 2017;Martin-Diaz et al, 2018). The main advantage of MLAs is that no mathematical model is needed for the system monitoring.…”
