WebThe model that was trained using only the w-dice Loss did not converge. As seen in Figure 1, the model reached a better optima after switching from a combination of w-cel and w-dice loss to pure w-dice loss.

WebMay 7, 2024 · The dice coefficient outputs a score in the range [0,1] where 1 is a perfect overlap. Thus, (1-DSC) can be used as a loss function. Considering the maximisation of the dice coefficient is the goal of the network, using it directly as a loss function can yield good results, since it works well with class imbalanced data by design.
