The confusion matrix of all models and original images and the corresponding gradient weighted class activation mapping (Grad-CAM) generated by ResNet18 of the representative patients. a The figure shows the number of patients in the test set who were correctly and incorrectly classified. b A 63-year-old man was diagnosed with pancreatic ductal adenocarcinoma (PDAC) with a high tumor stroma ratio (TSR). The tumor was in the pancreatic head. b, c Sixty-two-year-old man was diagnosed with PDAC with a low TSR. The tumor was in the pancreatic tail
