Id Subject Object Predicate Lexical cue
T421 0-142 Sentence denotes Based on the four blocks, two frameworks were designed for the classification task and regression task, respectively.Classification framework:
T422 143-208 Sentence denotes The CNNCF consisted of stage I and stage II, as shown in Fig. 3a.
T423 209-280 Sentence denotes Stage I was duplicated Q times in the framework (in this study, Q = 1).
T424 281-403 Sentence denotes It consisted of multiple ResBlock-A with a number of M (in this study, M = 2), one ResBlock-B, and one Control Gate Block.
T425 404-507 Sentence denotes Stage II consisted of multiple ResBlock-A with a number of N (in this study, N = 2) and one ResBlock-B.
T426 508-654 Sentence denotes The weighted cross-entropy loss function was used and was minimized using the SGD optimizer with a learning rate of a1 (in this study, a1 = 0.01).
T427 655-905 Sentence denotes A warm-up strategy58 was used in the initialization of the learning rate for a smooth training start, and a reduction factor of b1 (in this study, b1 = 0.1) was used to reduce the learning rate after every c1 (in this study, c1 = 10) training epochs.
T428 906-1044 Sentence denotes The model was trained for d1 (in this study, d1 = 40) epochs, and the model parameters saved in the last epoch was used in the test phase.
T429 1045-1066 Sentence denotes Regression framework:
T430 1067-1139 Sentence denotes The CNNRF (Fig. 3b) consisted of two parts (stage II and the regressor).
T431 1140-1384 Sentence denotes The inputs to the regression framework were the images of the lesion areas, and the output was the corresponding vector with five dimensions, representing the five clinical indicators (all clinical indicators were normalized to a range of 0–1).
T432 1385-1489 Sentence denotes The stage II structure was the same as that in the classification framework, except for some parameters.
T433 1490-1633 Sentence denotes The loss function was the MSE loss function, which was minimized using the SGD optimizer with a learning rate of a2 (in this study, a2 = 0.01).
T434 1634-1882 Sentence denotes A warm-up strategy was used in the initialization of the learning rate for a smooth training start, and a reduction factor of b2 (in this study, b2 = 0.1) was used to reduce the learning rate after every c2 (in this study, c2 = 50) training epochs.
T435 1883-2027 Sentence denotes The framework was trained for d2 (in this study, d2 = 200) epochs, and the model parameters saved in the last epoch were used in the test phase.
