Also, rather than using SGD, we used Adam optimizer as [37], [65] did. We found that in terms of stability and performance, Adam optimizer [37], [68] yielded better results than SGD while training big models like EfficientNet (B6, B7). Lastly, the polynomial decay learning rate ...

and the back-end framework was the Keras package with TensorFlow, which provides a high-level, user-friendly API for constructing and training models. Our model was trained for 30 epochs to ensure sufficient training without excessive overfitting. The Adam optimizer was chosen for its adaptiveness ...
This wrapping improved learning stability by helping the Rectified Adam optimizer escape from local minima and lowering the loss variance. Additionally, we applied a warm-up by setting the warm-up proportion to 0.1. Since we had two trainings, the learning rates were set as follows. (1) ...
