Graph adversarial networks
WebMissing data is a common problem in longitudinal studies due to subject dropouts and failed scans. We present a graph-based convolutional neural network to predict missing diffusion MRI data. In particular, we consider the relationships between sampling points in the spatial domain and the diffusion wave-vector domain to construct a graph. We then use a … WebAug 20, 2024 · The power of high throughput technologies cannot be fully utilized unless the multi-omics data with its intermodal relations are considered in studies. In recent years, generative adversarial networks (GAN) ( Goodfellow et al., 2014) has gained popularity in solving problems within the scope of computational biology.
