About "walkLength" of node2vec_spark

[HaominYu]

Hi

I have a question about the "walkLength"

OK, this file "Node2vec.scala"

My point of view has any problem?

Thanks

Best Yu

why the variable named as "pathBuuffer" already has 2 elements? actually is empty in my mind.

hi, aijianiula0601 You can look the previous code, or run it, have a try

Thanks

I think the total length of walks is (numWalks * walkLength) + 2.

[datazhen]

why the length of walks is |walkLength|+2 instead of |walkLength|+1？

I think @HaominYu is right. The graph initializes the pathBuffer size to 2, which contains the initial vertex and the next node. So the generated sentences length is definitely walkLength + 1.
