arXiv:2608. 03696v1 Announce Type: new Abstract: This work focuses on the problem of learning on temporal graphs, with particular emphasis on the task of clustering: obtaining coarse-grained representations by aggregating information from nodes, edges, and temporal dynamics - a task related to pooling in machine learning on graphs, or community detection in network science.

ComNetX is a solver‑agnostic hierarchical adaptation framework that localizes dynamic community detection updates by expanding, closing, and contracting affected communities. It preserves the context needed by high‑quality solvers while restricting computation to the changed graph regions. Experiments on six real networks and synthetic streams show that ComNetX maintains modularity close to full recomputation while achieving up to a 41.9× speedup on large graphs.

arXiv:2606. 07151v1 Announce Type: new Abstract: Traditional change point detection in dynamic networks assumes abrupt transitions between stationary states, overlooking scenarios of continuous evolution which arise in most real-world applications, such as social networks or physical systems.

High quality temporal graph benchmarks with rich semantics and ground-truth anomaly labels are essential for training graph neural networks, yet remain scarce due to privacy constraints and annotation costs. We present SAGA (Synthetic Agentic Graph Architecture), a system for generating large-scale, semantically rich temporal graphs via a four-phase pipeline.
