Official Codes for Graph Modularity:Towards Understanding the Cross-Layer Transition of Feature Representations in Deep Neural Networks.

We give an example to understand the dynamic graphs: we leverage pretrained ResNet18 (Top1 acc: 94.78%) on CIFAR-10 to extract feature representations. Then we set N = 50, k = 3 for dynamic graphs construction. The result is shown in the gif below: Note that nodes of the same color represent samples of the same class. The darker the color of the edge, the higher the similarity between the two corresponding nodes. The modularity curve of this dynamic graph:

modularity计算出来为负值是什么原因？

您好！我用的自己的数据集在resnet18上用了您的方法做了模块化程度的计算，提取的是relu层之后的特征，发现计算每层modularity会出现负值，这是什么原因呢？之后又尝试提取bn层后的特征还是有大量的负值存在，请问这是正常现象么？

一下是几次计算的结果，len（ modularity ）=17层 modularity: [-0.019196462265709934, -0.02271897533277316, -0.023171874127450653, -0.022470118258014187, -0.01645792102456704, -0.018011648884517804, -0.010016131091073174, -0.02012415433281817, -0.00993257811055065, -0.008657139629071227, -0.010918394908571914, -0.009388655522269241, -0.002584169673622568, -0.0005555165491241826, -0.012236681334620234, -0.013657490194399866, -0.001615048060680923]
