Tune node2vec parameters for link prediction demo

[PantelisElinas]

Description

Currently, the link prediction demo uses fixed parameter values, e.g., p=q=1 and several other parameters, for node2vec. We need to allow for these parameters to be tuned for improved link prediction performance.

User Story

As a: Research Engineer
I want: to tune the hyper-parameters of the node2vec algorithm
so that: I can achieve the highest performance in link prediction

• Code to tune node2vec hyper-parameters

@PantelisElinas is this still relevant?

[PantelisElinas]

Hi @youph

it is only relevant as a demo notebook or just extending the node2vec example to include tuning the p,q parameters. Since tuning the parameters is something that can be done outside our library, there is nothing to implement.

I agree, so perhaps this should be closed?

Hi @youph

I think yes, unless we have a need for a demo for parameter tuning, that honestly in this case, I don't think we need.
