Normalized RandomWalk returning k(G,G) = -1 #8

You should try a smaller lambda. A rule of thumb as noted by Viswanathan is setting lamda to the largest power of 10 which is smaller than 1/d^2, where d being the largest degree in the dataset.
Please install the latest grakel as I spotted an incosistency with the baseline. |
Got it. New version installed and example working. The only difference to your example is that the result of Thank you very much for your support and for the library! |
Hi,
I am using GraKeL as installed from the repository (grakel-dev, version 0.1a4). When playing around with RandomWalk, I found that the normalized kernel of a graph G with itself, k(G,G), is sometimes equals to -1. Here's a minimum working example to reproduce the result:
Why is this happening?
Thanks in advance for your support.
