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.
