“…A recent, prominent example of such an advance in machine learning is the application of convolutional neural networks (ConvNets), particularly in computer vision tasks. Thus, first studies have started to investigate the potential of ConvNets for brain‐signal decoding [Antoniades et al, ; Bashivan et al, ; Cecotti and Graser, ; Hajinoroozi et al, ; Lawhern et al, ; Liang et al, ; Manor et al, ; Manor and Geva, ; Page et al, ; Ren and Wu, ; Sakhavi et al, ; Shamwell et al, ; Stober, ; Stober et al, ; Sun et al, ; Tabar and Halici, ; Tang et al, ; Thodoroff et al, ; Wang et al, ] (see Supporting Information, Section A.1 for more details on these studies). Still, several important methodological questions on EEG analysis with ConvNets remain, as detailed below and addressed in this study.…”
