Some questions

[Mickeybaby]

Hello, thank you for your great work. I have benefited a lot from it. I'm a beginner in computer vision and person identification. There are many things I don't understand when I read your code. For example,I didn't understand this function： def linkage_calculation(self, dist, labels, penalty): ...... linkages = linkages.T + linkages - linkages * np.eye(cluster_num) intra = linkages.diagonal() penalized_linkages = linkages + penalty * ((intra * np.ones_like(linkages)).T + intra).T I don't know the details of such code. I am a graduate student in China.Is it convenient for you to leave your mailbox or wechat? I'd like to ask you some questions. Best wishes to you! 祝您一切顺利，生活幸福！

    你好啊，同学。我也觉得代码和论文有点不太一样，penalized_linkages按照论文来算的话应该不是这样算的，不过如果真的要算的话又要写两层循环（本人水平比较低，想不出用矩阵如何计算，哈哈），这样就会导致计算距离时间特别长。

    不过作者虽然计算了penalized_linkages ，但是后面好像也没用到。。。可能作者没有提交最新代码。也可能是我理解错了，不知道你有什么对代码的新的理解吗？
