“…Deep learning has grown and been used in many areas in the last decade, for example in the field of object recognition (Ghoreyshi, AkhavanPour & Bossaghzadeh, 2020;Ali et al, 2020), speech recognition (Deng, Hinton & Kingsbury, 2013;Li, Baucom & Georgiou, 2020), anomaly detection (Zhao et al, 2018), feature extraction (Lin, Nie & Ma, 2017;Rajaraman et al, 2018), auto-encoding (Pu et al, 2016).
