Table 2. Comparison of different optimizers on the segmentation performance of the proposed model on the LUNA16 dataset.

Optimizer	DSC	IoU	Precision	Recall
Adam (47)	0.7663	0.6401	0.7882	0.7775
AdamW (48)	0.7770	0.6518	0.8255†	0.7648
SGD (ours)	0.7921†	0.6662†	0.8102	0.7993†

^†, the optimal result. Adam, adaptive moment estimation; AdamW, Adam with decoupled weight decay; DSC, Dice similarity coefficient; IoU, intersection over union; LUNA16, Lung Nodule Analysis 2016; SGD, stochastic gradient descent.
