How to set adequate kernel bandwith #1

Open davisidarta opened 4 years ago

davisidarta commented 4 years ago

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! Davi

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. The link is: https://sidky.io/blog/diffusion-maps-part-2/ Hope this helps.
