Add a personalization vector option for personalized pagerank? #720

Open ddu1 opened 5 years ago

ddu1 commented 5 years ago

Maybe I missed it in the documentation, but I couldn't find an option to pass in a non-evenly-distributed personalization vector to the ppr algorithm, other than a list of sourceNodes (which implies evenly-distributed?) :

It would be a very nice feature to have, similar to what is implemented here.

I agree. I believe this is already discussed in #271 , where I suggest passing a named reference to a probability property on the nodes.
