    for second iteration , old authority of A should be 3/15 :)

    Very clear explanation , thanks

    so after the algorithm starts, it does not distinguish between authority nodes and hub nodes while adding up the scores. It is only after the k iterations are over, we again classify the nodes, and identify the more relevant authority and hub nodes as the ones with the largest scores.

    Could the authority score of page C be wrong? I get 0.37

    Wow, this is the clearest explanation of the HITS algorithm that I've found on the internet. Thanks.

    what does the meaning of converging in hit algorith?

    • @thepriestofvaranasi
      @thepriestofvaranasi 2 года назад

      It means that the hub and authority scores will stop changing in consecutive iterations.

    Does Google Algo use the HITS Algorithm? I think they do

      No. Check the PageRank Algorithm. HITS was an important predecessor though.

    Is there another way to normalize the initial authority and hub scores of 1 instead of dividing by the total amount of nodes? I have seen ap/c where c= sqrrt(sum(a^2) but do not know how to implement it

    Clear explanation. Thanks

  • @philh7204

    I think you're supposed to calculate the Hub score based on the current iteration's Authority score, not the previous iteration's.

      shall i assume this correction?

    • @adamlamay2074
      @adamlamay2074 5 лет назад

      agreed, it should be based on the new auth score
