《Grad-CAM:Visual Explanations from Deep Networks via Gradient-based Localization》这篇论文基于梯度为其可解释性做了一些工作,它可以显著描述哪块图片区域对识别起了至关重要的作用,以热度图的方式可视化神经网络的注意力。本博客主要是基于pytorch的简单工程复现。原文见这里,本代码基于这里。 1importtorch2importto...
A2, and A3 are weighted to make the final heatmap. In CAM, we weight these feature maps using weights taken out of the last fully-connected layer of the network. In Grad-CAM, we weight the feature maps using “alpha values” that are calculated based on gradients. Therefore, Grad-CAM ...
