“…GNNs and its variants have been employed for numerous applications such as recommendation systems ( Wu, Sun, Zhang, & Cui, 2020 ), protein interface prediction ( Fout, Byrd, Shariat, & Ben-Hur, 2017 ) and semantic segmentation ( Qi, Liao, Jia, Fidler, & Urtasun, 2017 ). For example, a combination of Convolution Neural Networks (CNNs) and graph relation networks have been used for brain connectivity network analysis ( Banerjee et al, 2020 ).…”
