How to set adequate kernel bandwith

[davisidarta]

Hello,

I'm trying to use your C++ implementation of Diffusion Maps with some of my data, which is really big (37k x 60k matrix). In readme you select the kernel bandwith as 3. How can I properly select a kernel bandwith on my data?

Best!

Hi Davi,
You can check out his blog post where he explains on choosing the kernel bandwidth and provides some insight on how dmaps is working.

Hope this helps.
