WebAug 22, 2024 · Functional network connectivity has been widely acknowledged to characterize brain functions, which can be regarded as “brain fingerprinting” to identify an individual from a pool of subjects. Both common and unique information has been shown to exist in the connectomes across individuals. However, very little is known about whether … Webautoencoder for Molgraphs (Figure 2). This paper evaluates existing autoencoding techniques as applied to the task of autoencoding Molgraphs. Particularly, we implement existing graphical autoencoder deisgns and evaluate their graph decoder architectures. Since one can never separate the loss function from the network architecture, we also
