 *Visual 3: PyTorch_Geometric model performed well on predicting final fungal community member presence*
 Here, we trained one graph per microcosm, where each taxon is a node with donor and resident abundance/presence features. A 2-layer GraphSAGE model learns taxon embeddings from these features and optional taxon-taxon association edges, then uses two output heads to predict each taxon’s final presence probability and final log-abundance.
