About code of PDD in SDCA

[wangxyustc]

Dear Author,

Thanks for your fantastic paper, I think it is very interesting. And I notice that you provided the PDD for visualization of the embedded features in your paper , but I did not find it in your code. Whether it is clan or fada for ccd (Cluster Center Distance ,Class Center Distance) code has not been released, PDD considered more details, I am going to use PDD to analyze some papers .Could you please upload the implementation on how to perform the PDD in your codebase?

Looking forward to your reply.

Best Regards, Qianmo
