Who has the biggest in Bayesian Nonparametrics?

This very fine title quotes a pretty hilarious banquet speech by David Dunson at the last BNP conference held in Raleigh last June. The graph is by François Caron who used it in his talk there. See below for his explanation.

After the summer break, back to work. The academic year to come looks promising from a BNP point of view. Not least that three special issues have been announced, in Statistics & Computing (guest editors: Tamara Broderick (MIT), Katherine Heller (Duke), Peter Mueller (UT Austin)), the Electronic Journal of Statistics (guest editor: Subhashis Ghoshal (NCSU)), and in the International Journal of Approximate Reasoning (proposal deadline December 1st, guest editors: Alessio Benavoli (Lugano), Antonio Lijoi (Pavia) and Antonietta Mira (Lugano)).

BNP is also going to infiltrate MCMSki V, Lenzerheide, Switzerland, January 4-7 2016, with three sessions with a BNP flavor, in addition to plenary speakers David Dunson and Michael Jordan. The International Society for Bayesian Analysis World Meeting, 13 -17 June, 2016, should also host plenty of BNP sessions. And a De Finetti Lecture by Persi Diaconis (Stanford University).

Below, François’ description of his graph

  • nodes are speakers at BNP9 and / or BNP10
  • edges link co-authors
  • node and text sizes are proportional to node degree (nb of co-authors)
  • visualization with gephi (spatialization Yifan Hu)

Some comments (by François)

  • it’s most probable that he missed connections
  • there’s obviously a selection bias by only taking on speakers of the last two BNP meetings
  • the graph is obtained by a simple “one-mode projection” of the bipartite graph authors-articles; this projection isn’t optimal since two authors of a six authors paper may not have really collaborated; Newman proposed another type of projection which weights by the number of co-authors (eg a weight of 1/3 each for a three authors publication)
