Researchers have developed new distance-based Graph Autoencoder (GAE) variants designed to improve dynamic graph embedding by accounting for structural heterogeneity among nodes. These methods incorporate structural penalties into the reconstruction loss, specifically a hub penalty based on degree centrality and a penalty derived from Natural Community Local Intrinsic Dimensionality (NC-LID). Experiments demonstrated that integrating NC-LID-based regularization consistently enhanced reconstruction performance compared to baselines without structural regularization or with hub-aware regularization, highlighting NC-LID as a valuable structural signal for GAEs in dynamic graph settings.
