Integrated Gradients and All its variants

The pattern overlapped well with a large-scale meta-analysis and we observed Integrated Gradients (IG) achieved the best Dice overlap. Recently there are more and more IG variants have been proposed. In this article, I am going to use the model and data achieved by our paper and further investigate the performance of different IG variants. I will briefly introduce different IG methods as well as some other possible IG variants. Integrated Gradients is calculated by integrating the gradients of all interpolated images along a linear path from the baseline to the input image.
