Thank you for the wonderful lecture Sir. While writing the centrality vector X(t) as a product A^t * X(0), how do we initialize X(0), or rather, do we need to initialize X(0) ? My thinking was something along these lines. We just assume X(0) to be anything and eventually what we end up wanting is the eigen vector corresponding to the largest eigen value, and not even the multiplier term (since we are measuring relative centrality), the actual value of X(0) is moot ? Could you please clarify this?
Thank you so much for this great explanation, could you please explain why ignore lambda (t)*C1 what you mean by "only care about the relative centrality" which rule that justify that you can ignore absolute values
Because centrality is essentially the "importance" of nodes (actors) in the network. Usually, we are interested in knowing which node is important than the other one. This importance does not change if centrality is multiplied by a constant factor. For instance, suppose in a social network, you want to give away a new product to the most important users, so they can influence others to buy the product... Then, the relative importance is all that matters...
You all probably dont care but does someone know a way to log back into an Instagram account..? I stupidly lost the login password. I would love any tips you can give me!
@Philip Brady I really appreciate your reply. I got to the site on google and I'm waiting for the hacking stuff atm. Looks like it's gonna take a while so I will reply here later with my results.
Beautifully done Mr. Ruths!
Nicely explained!
Thank you Sir. You have made it crystal clear
Thank you, great explanation!

@Philip Brady It worked and I now got access to my account again. I'm so happy!
Thank you so much, you saved my account !
great explanation! :)
good job :]
thanks!
