Background: The study of task-driven dynamic adaptive graph sparsity patterns in Alzheimer's disease (AD) analysis is great importance, as it allows for better focus on regions and connections interest enhances task sensitivity. Methods: In this study, we introduced a model (called radiomics-based morphological brain network [Task-radMBNet]) AD diagnosis based (radMBN). Specifically, the Task-radMBNet was established by devising connectivity feature-based convolutional (GCN) channel...

Brain-Machine Interfaces (BMIs) convert paralyzed people's neural signals into the command of neuro-prosthesis. During subject's brain control (BC) process, patterns might change across time, making it crucial and challenging for decoder to co-adapt with dynamic patterns. Kalman Filter (KF) is commonly used continuous in BC. However, if become quite different compared training data, KF needs a re-calibration session maintain its performance. On other hand, Reinforcement Learning (RL) has...
