Directed information structure

The good news is that we recently received a notice of acceptance of an abstract we submitted to CNS*2009 (July 18-23) in collaboration with John-Dylan Haynes and Jakob Heinzle from the Bernstein Centre for Computational Neuroscience (BCCN) in Berlin.

Titled "Directed information structure in inter-regional cortical interactions in a visuomotor tracking task", it deals with a method for identifying directed information structure between distinct regions (of variables) in a large multi-variate set. The method identifies an interesting hierarchical structure for the given visuomotor task.

My supervisor will be at CNS to present the poster, and the abstract will be included in a supplement to BMC Neuroscience soon. We're currently working on a more complete journal paper reporting on this experiment.

CNS*2009 should be a good meeting, particularly the Methods of Information Theory in Computational Neuroscience workshop. Wish I was going!

ECAL and ECCS calls for papers

Just thought I'd share two calls for papers for conferences that I will be / have submitted to this year.

The European Conference on Complex Systems (ECCS09) will be held from 21-25 September 2009, at the University of Warwick, UK. I've never been to ECCS before, but I've heard good things from several people about it. I like the way it appears to be a real melting pot of all areas of complex systems science, so I'm looking forward to seeing some interesting perspectives there. On that note, I think there will be some interesting applications related papers there, e.g. in the Policy, Planning and Infrastructure track. I also like the tiered submission structure, where you can submit 2, 6 or 15 page papers, and (if accepted) get a poster, 20 min or 40 min presentation: it gives you choice, and appropriate relative reward for work. We've submitted a paper on cascading failures in energy networks (more details if we're accepted). The first submission deadline has passed, though they have two more deadlines coming up (19/4 and 3/5): apparently slots will be filled on a "first arrival - frist serve policy".

The 10th European Conference on Artificial Life (ECAL2009) will be held from September 13-16 2009 in Budapest, Hungary. I was at the last ECAL in Lisbon in 2007 and thoroughly enjoyed it. It's a good crowd, with a nice mix of biologists and computer scientists. We're currently working on a paper combining some of my work on information dynamics with my PhD colleague Mahendra Piraveenan's work on network topological measures: this is something I had wanted to do for a while, but isn't in the form I thought it would be (nothing wrong with that though). More details if we're accepted. Anyway, ECAL are now following the lead of ALifeXI in allowing abstract only submissions (which I think is fine in principle), and allowing both to have presentation slots (this I'm not sure about - I had the impression that some, not all, of what came through the abstract only channel was under-prepared; I prefer the ECCS approach). Paper submission is by April 30.

Hope to see you there! (assuming we get accepted...)
