Aplicando algoritmos genéticos a un controlador ‘fuzzy’ para una gestión adaptativa del tráfico

Recientemente se ha aceptado el artículo “A hybrid Fuzzy Genetic Algorithm for an adaptive traffic signal system” en la revista open-access Advances in Fuzzy Systems. En él participamos varios de los investigadores de GeNeura.

El abstract es:

This paper presents a hybrid algorithm that combines Fuzzy Logic Controller (FLC) and Genetic Algorithms (GAs) and its application on a traffic signal system. FLCs have been widely used in many applications in diverse areas, such as control system, pattern recognition, signal processing, and forecasting. They are, essentially, rule-based systems, in which the definition of these rules and fuzzy membership functions is generally based on verbally formulated rules that overlap through the parameter space. They have a great influence over the performance of the system. On the other hand, the Genetic Algorithm is a metaheuristic that provides a robust search in complex spaces. In this work, it has been used to adapt the decision rules of FLCs that define an intelligent traffic signal system, obtaining a higher performance than a classical FLC-based control. The simulation results yielded by the hybrid algorithm show an improvement of up to 34% in the performance with respect to a standard traffic signal controller, Conventional Traffic Signal Controller (CTC), and up to 31% in the comparison with a traditional logic controller, FLC.

Esperamos que os guste (y que lo citéis, claro :D).

GeNeura en la Noche de los Investigadores 2015

GeNeura estuvo presente dentro de la Noche Europea de los Investigadores en el stand de la actividad El Ojo que todo lo ve. En este evento estuvimos realizando difusión de los proyectos SIPESCA, MOSOS, PETRA y el recientemente solicitado SiMoPE. Dentro del stand estuvimos mostrando el estado de los proyectos, sus avances, los dispositivos de captación, y los datos de dispositivos móviles que habíamos ido tomando. Tuvo una gran afluencia de público, que participó de forma activa a través de preguntas y opiniones. Además, estuvimos midiendo el paso de las personas que estuvieron asistiendo al evento con uno de nuestros dispositivos.

YAPC::Europe 2015: Something dies in your soul when a friend is leaving.

The European Perl conference of this year is over.


During the week from 31-Aug-2015 to 5-Sep-2015, Granada has been hosting the YAPC::Europe 2015; a Perl conference in which GeNeura Team has been one of the main organizers. Along these days, more than 250 professionals, most of them Perl developers, have been talking, listening, discussing, laughing, singing (at least Larry Wall did it), offering employment opportunities, and sharing drinks and tapas around a single main topic: Perl.

It is never easy to organize a conference, and YAPC has a singularity: is  probably-the-cheapest-international-conference (regarding the prices for delegates) I’ve ever been. Anyone having a talk accepted (except for lightning talks) received a free registration which included all the goodies (bag and T-Shirt, among others), and tickets for pre-conference dinner, lunches and gala dinner. There were also some courses organized under the scope of the conference, but registration was separate. Having all of this in mind, YAPC Europe wouldn’t be possible without the sponsors. For this reason, first of all, let us thank  all the companies and people that have supported this event (you can see all of them at http://act.yapc.eu/ye2015/our_sponsors.html): nothing could have been written about this conference without their generosity.

The venue for YAPC::Europe 2015 has been the Faculty of Sciences of the University of Granada. For this reason, the conference started with the pre-conference dinner, where all of us shared a some bits (in fact, a good amount of) pizzas seated on the grass of the venue’s backyard. Thus, from the very first moment, we realized that YAPC is mainly designed to keep people, the community, in touch. More than sharing knowledge (although it is shared), showing solutions (and they were shown), or talking about “one’s book”, YAPC allows you shaking the hands that wrote the CPAN module that saved your project a few months ago, or seeing the smile of that costumer whose business mainly depends of Perl’s good (unique?) programming features.

During the three days the conference lasted, plenary talks took place both at first and last hours. Thus, the central hours were dedicated to parallel sessions with talk lasting 20 or 50 minutes, with a small gap between them, so that people can move from room to room attending to their favorites talks. It’s rather difficult, if not impossible , to make a summary of all of them, so, both the schedule and list of accepted talks will be available for a long time, just in case anyone is interested.

Last day was probably the big day. Larry Wall was talking about Perl 6… Well, and also about lot of things related to Tolkien’s books and their similarities with Perl 5 and Perl 6. Larry invited us to the party, i.e., the upcoming release of Perl 6, that will be available in Christmas (in fact, this was not the first time he pronounced this sentence… but it’s the first time that he indicates the exact year for those “Christmas”, and is 2015!!!). We’ll never would be able to thank him enough for being with us in Granada, and will never forget him… as well as their hats.

Together with Larry’s talk, probably lightning talks have been the most important discovery in this conference. Far away from extremely, perfectly, and strictly organized and exposed speeches, lightning are 5-minutes length talks that give the opportunity to show new CPAN modules (or also preventing people for spending their time writting modules for solved problems, i.e., CGI.pm ) , your analysis of the use of a given module, the importance of making web analytics… and, most of all, of being in contact with Japanase developers (sorry, fast developers). Lightning talks are dynamic, illustrative, interactive, fun, necessary… essential!!!!

Finally, as this YAPC::Europe was devoted to art and engineering, let us say “good bye” to the attendees with two songs. First one is a typical Andalusian song, that could be translated into “Something dies in your soul when a friend is leaving”. But, as far as I’ve could seen, probably the best song that reflects what programming in Perl means is Joe Cocker’s “With A Little Help From My Friends” (https://www.youtube.com/watch?v=_wG6Cgmgn5U)… Maybe Frodo Baggins and the Fellowship of the Ring would fully agree with me… maybe not.

BTW, YAPC::Europe 2015 is done; so is this entry. (Some other thing I learned in a lightning talk – see http://www.brepettis.com/blog/2009/3/3/the-cult-of-done-manifesto.html)

GeNeura organizes the YAPC::Europe 2015 conference

GeNeura Team is one of the organizers of YAPC::Europe 2015 conference, an international event where about 300 people are talking, learning, practicing and arguing about Perl, the programming language.

This event is being held at the Faculty of Sciences, in the University of Granada, and is taking place from 2-sep-2015 to 4-sep-2015.

This year, the final talk will be given by Larry Wall!!

Charla Problema de Diseño de Meta-heurísticas

Este lunes 25 de Mayo presenté una charla acerca de nuestros trabajos en Diseño de Metaheurísticas basado en el uso de sintonizadores.
La primera parte describe la motivación para el estudio de este problema, la formulación del problema propiamente tal y una clasificación de las técnicas.
En la segunda parte se establece un acercamiento para utilizar herramientas de sintonización para evaluación de distintos diseños. Se especifican los acercamientos previos utilizando sintonizadores conocidos en la literatura y se muestran los resultados obtenidos para el re-diseño de un algoritmo basado en sistemas inmunes que resuelve el problema de calendarización de torneos relajado (RTTP).

Acá les dejo las diapositivas de mi presentación.
