Graph topology learning
WebJul 29, 2024 · Machine learning models for repeated measurements are limited. Using topological data analysis (TDA), we present a classifier for repeated measurements which samples from the data space and builds a network graph based on the data topology. A machine learning model with cross-validation is then applied for classification. When test … WebNov 5, 2024 · In this work, we present a new topology-adapting deep graph learning approach for accurate anatomical facial and medical (e.g., hand, pelvis) landmark detection. The proposed method constructs graph signals leveraging both local image features and global shape features. The adaptive graph topology naturally explores and lands on …

WebApr 11, 2024 · Learning unbiased node representations for imbalanced samples in the graph has become a more remarkable and important topic. For the graph, a significant challenge is that the topological properties of the nodes (e.g., locations, roles) are unbalanced (topology-imbalance), other than the number of training labeled nodes … WebJan 1, 2024 · The three branches correspond to the topological learning for global scale, community scale, and ROI scale respectively. In Sect. 2.2, data processing was performed on each subject. With the BFC graphs constructed by the preprocessed fMRI data, the TPGNN framework was designed for the multi-scale topological learning of BFC (Sect. …
