This paper takes on a key challenge for recommender systems — how to deliver suitably diverse and personalized results without compromising the accuracy of the recommendations. Most authors have described this as requiring a trade-off between diversity and accuracy: we show instead that it’s possible to simultaneously enhance both with a suitable hybrid algorithm.
The first of the Liquid Publication Project’s deliverables, a report into the state of the art of many different aspects of scientific publishing and related or relevant systems and technologies. Section 3 was the Fribourg group’s responsibility, for which I and Matúš Medo were the principal writers. I also made small contributions to various other sections of the report.

Cannot confess to much involvement in this one — some nice Chinese colleagues at Fribourg asked for my advice and input on this fun little paper on promoting cooperation in a spatial multi-agent version of the Prisoner’s Dilemma.

This was the fruit of a 2-month internship at the Neural Network Physiology Lab run by Dietmar Plenz at NIMH/NIH.
A little tribute to a dear friend. This is a playful paper discussing the idea put forward by Per Bak and Dante Chialvo that potentiation (strengthening) of synapses as a reward for good behaviour carries with it the possibility of addiction and inability to adapt. (It also marks the public debut of my middle name on scientific publications…;-)
Laureti, P., Ruch, P., Wakeling, J. and Zhang, Y.-C. (2004) The Interactive Minority Game: a Web-based investigation of human market interactions. Physica A331: 651-659
This paper describes a psychology/economics experiment examining human decision-making in financial market-type situations. By using a Web-based interface we allow humans to interact with a simple economic game (the Minority Game), and we study how they make use of information contained in the market history. An article on the work appeared in Technology Research News Magazine (5 November 2003), and it was mentioned in Mark Buchanan’s New Scientist article ‘It’s the economy, stupid’ (10 April, pp. 35–37). The game is sadly long offline; someone bug me to re-implement it please!
Wakeling, J. (2003) Order-disorder transition in the Chialvo-Bak ‘minibrain’ controlled by network geometry. Physica A325: 561-569
A snappy title I’m sure you’ll agree!-) This paper ‘does exactly what it says on the tin’, demonstrating a phase transition in the minibrain neural network between an ordered phase where learning is possible, and a disordered phase where there is a limit on learning ability. The transition occurs subject to the ratios of the size of different layers of neurons (rather like the phase transition observed in Hopfield networks on the basis of neural connectivity). Mostly numerical work here (actually the minimal analytic approach in this paper contains a whopping great error, porca miseria) but an analytical justification is available in my PhD thesis.
Ruch, P., Wakeling, J. and Zhang, Y.-C. (2002) The Interactive Minority Game: instructions for experts. Working paper, arXiv:cond-mat/0208310
This is a working paper we put out in the early days of the Interactive Minority Game, a Web-based interactive market game, to describe what we were doing for the econophysics community. The description of the game setup and technical details is now out of date as we changed a number of aspects of the game before concluding our research; our Physica A paper describes the game setup and results as they now stand.
This fun and rather philosophical paper discusses the need to take into account the surrounding environment when investigating intelligence (and thus neural systems). A lot of people seemed to think this was rather an important paper (and others were rather annoyed by it). Articles on this work were published in Physics News Update 563 (31 October 2001), New Scientist (17 November 2001), wired.com (26 November 2001) and Technology Research News Magazine (5 December 2001), and it was selected as the Econophysics Forum Paper of the Month (February 2002).
