Image encoder choice significantly impacts GCN performance in breast ultrasound classification

Researchers have investigated the impact of different image encoders on the performance of graph convolutional networks (GCNs) for breast ultrasound classification. The study found that higher-capacity encoders, including both convolutional and transformer-based architectures, consistently improved graph homophily and downstream classification metrics such as accuracy, AUC, sensitivity, specificity, and F1-score. The research also established a strong correlation between test-set graph homophily and classification accuracy, suggesting that improved representation quality from the encoder is a key factor in the performance gains.
