A call to update the Lake Arrowhead graph!

Please read Cleve Moler’s blog post about the Lake Arrowhead matrix too and look at the comments. That’s what got this all started!

We’d like to produce a new version of this matrix with information from 2013. Once I have that, I’ll run a a few matrix-based link-prediction techniques that Gene would have enjoyed and report the results. (You can see the preliminary results on the linked page.)

These have already born fruit as they revealed a missing link between Boley and Golub (“A modified method for reconstructing periodic Jacobi matrices” Math. Comp. 42(165):143-150, 1984.)

Some other new links I found by looking at Gene’s CV

  • Golub and Benzi
  • Golub and Pan (is JY Pan the same?)
  • Golub and Funderlic
  • Golub and Strakos
  • Golub and Chandrasekaran
  • Golub and Bai (was this Bai Zhaojun?)
  • Golub and Moler
  • Golub and Park (assuming Haesun)
  • Golub and Hansen
  • Golub and Gragg
  • Golub and Starke

Some of these were predicted by the metrics! Awesome!

And these links were missing from the original!

  • Golub and Boley
  • Golub and Smith (assuming it was L. Smith at the meeting)
  • Golub and Stewart (assuming it was G. W. at the meeting)

Key questions

  • Who was the “Ng” at the meeting? Gene and Michael Ng authored a paper together, so that’d be another link if it was the same one — but this is a pretty common last name.
  • Was it L. Smith at the 1993 meeting?
  • Was it Pete Stewart at the meeting?

While I have a copy of Gene’s CV, the key issue is finding all the links between the other 103 people in the graph! So we need some help.

If you are one of these authors and you’ve co-authored a paper with someone after the original Lake Arrowhead matrix from 1993, can you post a note either on my blog or on Cleve’s blog with any additional co-authors?

Alternatively, if you’d like to email one of us your CV, we’ll do all the work for you! I reported the updates from Golub’s CV already.

Update I created a GitHub repository for these edits. If you are feeling brave, head to the arrowhead-graph repository click on “arrowhead-new” (if the paper occurred in 1993 or afterwards) or “arrowhead-missing” (if it was missing from the original, i.e. a pre 1993 reference). Then click “edit”. You’ll have to sign up for an account (which is good to have anyway!), but then it’ll automatically edit the file and tell me your changes.

    Higham and A. Trefethen, Higham and N. Trefethen, Higham and Bojanczyk, Higham and Van Dooren, Higham and Kenney, Higham and Hammarling are all post-1993.

  2. Steve L says:

    In your link prediction demo, the first line in the “Katz scores” section is incomplete. I was able to find the Wikipedia page on “Katz centrality” (on the third page of Google results; apparently the Katz index is much more commonly used or cited as a medical evaluation technique) but for ease of reference can you complete the demo description? Thanks!
