The recent developments in the field of neuroimaging and machine learning for disease diagnosis and understanding brain functionality have shown significant progress. A notable trend is the increasing application of graph neural networks (GNNs) and latent representation models to analyze complex brain network data. These approaches aim to capture both short- and long-range dependencies within brain networks, offering a more integrated understanding of brain-wide communication. Additionally, there is a growing emphasis on the use of ensemble models and dimensionality reduction techniques to improve the accuracy of disease detection from high-dimensional datasets. These advancements not only enhance our ability to diagnose and monitor diseases like major depressive disorder (MDD) and chronic liver disease but also deepen our understanding of the brain's computational tasks and neural disorders.
