Node emdeddings:graphSage

I am trying to use node embeddings I would like to apply graphSage algorithm..
Is there any reference for graphSage so that I can understand more on this algorithm and so i can apply this in my data..
I need to understand how hyper parameters are used to tune the graphSage


I would check out the documentation:

Or the original publication:

For a more general primer on graph embeddings, our developer's guides are really good:
