“…With excellent performance in imaging, speech, machine translation, etc ( Minar and Naher, 2018 ), DL has entered into many biological fields, including genes, proteins, metabolites, microbiomes, and population-wide genetic variation, synthetic biology, drug discovery, and diseases ( Alkawaa et al., 2018 ; Golkov et al, 2020 ; Hill et al., 2018 ; Zeng et al., 2021 ). The promising DL methods include capsule networks ( Inokuma et al., 2010 ; Xi et al., 2017 ), multitask learning ( Antropova et al., 2017 ; Wang et al., 2015b ; Zhu et al., 2016 ), GANs, self-encoding decoders ( Marchi et al., 2015 ; Wang et al., 2018 ; Xu et al., 2014 ; Yao et al., 2017 ; Zhao et al., 2016 ), Variational AutoEncoders (VAEs) ( Panych et al., 2015 ), Long Short Term Memory Networks (LSTMs) ( Baytas et al., 2017 ; Gers and Schmidhuber, 2001 ; Graves et al., 2005 ; Yildirim, 2018 ), transfer learning ( Fernandes et al., 2017 ; Pan and Yang, 2010 ; Paul et al., 2016 ; Zoph et al., 2016 ), deep neural networks (DNNs) ( Yoshioka et al., 2014 ), and CNNs ( Horváth et al., 2017 ; Luo, 2015 ; Parashar et al, 2017 ; Wang, 2013 ; Xue et al., 2016 ).…”
