I have read "Fun and Games" by Ken Binmore. I think the book is good, but I do not share some of his views, specially regarding Bayesian rationality and its relevance in Game Theory.

I am now reading "Modeling Bounded Rationality" by Ariel Rubinstein. I share his views to some point. I think that a lot experimental work (analyzing how we, humans, take decisions) has yet to be done before we can have conclusive results on that area.

Yesterday I received some more food for my brain. My reading list now looks like this (growing):

  • Game Theory: Analysis of Conflict, by Myerson (I have not yet received any of the Fudenberg books, so I will start by Myerson, that I have at hand and looks really well written)
  • Game Theory, by Fudenberg and Tirole
  • The Theory of Learning in Games, by Fudenberg and Levine
  • Evolutionary Games and Population Dynamics, by Hofbauer and Sigmund
  • Cooperative Game Theory and Applications, by Inma Curiel
  • Evolutionary Game Theory, by Weibull
  • The complexity of cooperation, by Robert Axelrod
Bufffff, quite a lot of work for Xmas!!


I am preparing the slides for my PhD defense taking place in Dec, 15th. Boring!


I have started to teach "Scripting Languages". First class has been about why using scripting languages. Next talk I will start with Ruby

PhD experiences

I have read Peter McBurney notes on what means doing a PhD. it is worth reading it if you are thinking in engaging in a PhD coming from a successful business carreer.


Yesterday I went to an exposition by "Colectivo Psicoplástico" at La Xina Art. Thanks to lagatacristi for inviting me and for the nice piece of chat.


I have been reading "Decisions with Multiple Objectives" by Keeney and Raiffa. The book introduces Decision Theory and after that focuses in the elicitation of multiattribute utility functions. I think I have achieved a general understanding of decision theory. Now I would like to continue learning and my steps point to a particularly interesting subarea of Decision Theory: Game Theory. My reading list for the area includes:

  • Fun and Games: A Text on Game Theory, by Ken Binmore
  • Game Theory, by Fudenberg and Tirole
  • Game Theory: Analysis of Conflict, by Myerson

I am also skimming through different network programming books to prepare a new subject I am teaching from February to June.

And finally I am still reading and rereading the Pickaxe Ruby book.


I am preparing some new experiments to submit a paper with my results in TAN induction to the Journal of Machine Learning Research.

I am also writing the slides for the Ruby course. That is fun, but is taking a lot of my time.


Today I have managed (thanks due to Jaume Timoneda) to install debian on my new desktop computer at work.

CCIA 2003

Thursday I am travelling to Mallorca. I am attending the Catalan Conference on Artificial Intelligence and we do stay there the weekend just for fun.

Group Decisions

I have read something more on Group Decisions. Specially interesting and worth reading are the works of Raiffa and an article named "Preference aggregation after Harsanyi's". Harsanyi's theorem provides a possitive result. I will try to work on how to take advantage of it in multiagent systems. Still very inmature ideas


Monday, Victor Eruhimov, from Russia Intel Research Center was invited by me to give a talk about PNL (Intel's Open Source Probabilistic Network Library) at IIIA. It was very interesting. I am anxiously waiting for the Linux alpha release that is promised for next week


I got some mass spectrogram data from Oryzon Genomics that I am starting to analyze. I am implementing the spectrogram analysis and classification software in Ruby. First foundamented Bayesian analysis did not work very well, whilst some adhoc ideas did perform reasonably. More work is needed to refine Bayesian approaches or to understand what is wrong in the formalization of the problem.

Yesterday I received the good news that my thesis has been accepted for defense. I will defend it on mid-december if nothing happens. I am VERY happy about that because the revision period has lasted for six months, much longer than I expected.

I am learning MS Access, because I have to teach "Introduction to Databases" this semester. Fortunately, I also have to learn Ruby because I am also teaching "Scripting Languages". Learning is fun, even if it is MS Access.

I have been reading about Decision Theory, Game Theory and about Group Decision Theory. I have discovered the amazing Arrow's Theorem, that states that no strategy can make a group choose consistently and democratically from a set of alternatives.

I have also had my first contact with Oryzon genomics, a biotech company on the surroundings and I learned a lot of SELDI-TOF mass spectrometry.

Tomorrow we are travelling to Santander to be with my niece on its Birthday.

Back to work after my honeymoon. :o(

I have been proposed to be in the international committe of ICCI 2004.

I am working in a paper for SIAM DM (deadline Sept. 15)

I have updated my home page.

I am working hard to end up my PhD thesis document. I have to remake some of the experimental work, and that takes ages and lots of effort. I am lucky to have the cluster available. I hope to finish it before I go on holidays. I think I am a bit too stressed.

I have had access to the Linux cluster in the department for the first time. Now I know how it feels the pover of 32 dual xeons under my keyboard :o)

I have to remake part of the experimental work in my thesis to homogeneize its presentation. This is easy due to Durin.

Lately I have been reading a lot. I have been through "Learning Kernel Classifiers" by Herbrich (which I strongly recommend), "The Nature of Statistical Learning Theory" by Vapnik (which is more biased but good also) and the first chapters of "Causality" by Pearl. Now I am reading "A Probabilitic Theory of Pattern Recognition" by Devroye et. al.

I am also reading "The Ruby Way" to prepare my next Ruby course (thanks to fxn).

Long since last post. Recent news:

I have been to St. Augustine, Florida for the FLAIRS 2003 conference. It was very nice, a mix of local and international that kept a good technical level at a very friendly atmosphere. My presentation was kind of boring and uninteresting. I have to learn how to keep the audience interest.

I have been accepted a paper for the International Conference on Machine Learning to be held in Washington DC in August. I am happy, because this is one of the most prestigious Machine Learning conferences and I have never been to it. I am looking for a cheap travel option to see NY with Elena and then go to Washington to end up relaxing in Punta Cana (that is going to be my honeymoon). Today I have been finishing the experiments for the final version. I was asked by the reviewers to include statistical significance testing for the results. The results are significant with a 95% confidence.

Today I have given a class about "Artificial Intelligence and Machine Learning" in the middle of the "Ronda Universitat" in Barcelona. It was fun.

I am reading Steffen Evers "An Introduction to Open Source Software Development".

I have been asked by two of my students (esteve and angels) to give a class in the middle of the street tomorrow in order to protest against Iraq's invasion. Yes, fxn, two of your future students are also in advogato and you still have not certified them :op

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
