On March 19th and 20th 2009 took place the annual meeting of the MID-CBR (Marco Integrador para el Desarrollo de Sistemas de Razonamiento Basado en Casos, TIN2006-15140-C03) a coordinated project by the Instituto de Investigación de Inteligencia Artificial (IIIA-CSIC; Main Researcher: Dr. Enric Plaza), the Universidad Complutense de Madrid (GAIA-UCM; Main Researcher: Dra. Belén Díaz-Agudo) and the Universitat Ramon Llull (GRSI-URL; Main Researcher: Dra. Elisabet Golobardes). The aim of this meeting was to summarize all the work done, throughout the last year, reported all the articles published and the communications presented in the most relevant journals and conferences of the CBR community. There were also explained the current lines of research and there were proposed future collaborations. In particular, we can highlight some events of the agenda for the first day: Enric Plaza (Research Coordinator) started the meeting presenting the achievement degree of the project goals and the assessment of the different pattern’s project outcome. All this information was reported in the official annual report sent to the Science and Technology Ministry.


A. Sánchez, H. Gómez, P. González, E. Golobardes, J.L. Arcos, J. Recio, C. Garriga, E. Armengol, E. Plaza, M. Castanys, G. Corral, B. Díaz, A. García, D. Vernet, A. Fornells

Then, Juan Antonio Recio and Antonio Sánchez, two members belonging to the GAIA-UCM group presented the last version of jcolibri2, where the most relevant changes are related to their work on textual CBR and the incorporation of templates. There were also presented their beginning in incorporating planification based on descriptive logic for the reuse phase in CBR systems. Secondly, Albert Fornells and Guiomar Corral presented the most recent advances in the MID-CBR project achieved by the GRSI group, both in the melanomas domain and the telematic domain. Thirdly, Eva Armengol and Josep Lluís Arcos from the IIIA introduced their research work in extraction and explanation in lazy domains and in using introspective reasoning to improve CBR system performance, respectively. Enric Plaza was in charge of introducing their first results on Social Choice CBR (based on social networks topologies), where different methodologies inspired on argumentation and poolcasting.
Finally, Pedro González, member of the GAIA-UCM group, presented an overview of their research in artificial intelligence mainly applied on the virtual reality (games) domain.
During a coffee break all the MID-CBR team took the opportunity to visit the laboratory Media Lab La Salle of La Salle Campus.
The last day all the MID-CBR team participated in a brainstorming where all the new research lines were discussed, and where new lines and collaboration were opened. The discussion will make easier the definition of our future work in the CBR framework, making possible the transition from the MID-CBR to futures projects.

Prof. León Chua visited Barcelona to preside over the examining committee of one of our former members and current collaborators, Giovanni Pazienza. On this visit, he had time to share his main discovery with us in the talk: “Memristor: 37 years later”.
Through an unusual presentation, overhead transparencies, amusing jokes, technological explanations hidden in works of art, this endearing scientist brought the technology of the future closer to us.


To know more about this conference and the memristor, please refer to the full “El País” article.

This week started with the master thesis (PFC) presentation of one of our scholarship holder, Marc Aguilar. I could not attend his presentation but the attendants praised the talk and told me that Marc was fantastic and confident. For this reason, I decided to interview him and you will find below his impressions.

 

Interviewer: “Marc, were you nervous on Monday?”
Marc: “Well, as a person who is not used to speaking in public, a speech always makes you feel a bit nervous. However, after the first minutes, I forgot about that and felt really comfortable.”

Interviewer: “How was the presentation?”
Marc: “The last days before the presentation, Albert Fornells and I had planned and debated what the content of it and the main concepts that had to be clear to the jury and the rest of the audience should be. I think I managed to explain almost everything we agreed to in a way I liked it. Obviously, there are thousands of ways in which to improve a presentation and I will work to develop better skills in that field.”

Interviewer: “Could you briefly explain what your project consists of?”
Marc: “My project is related to melanoma’s cancer, which is the most lethal skin cancer nowadays. In the framework of a bigger project named MID-CBR (TIN 2006-15140-C03-03), the collaboration between Hospital Clínic i Provincial de Barcelona (HCPB) and GRSI arose to help them face this disease and so did the opportunity to develop what finally became my project.
In it, a conceptual model of the melanoma’s domain was defined –extracting the knowledge from the hospital experts–, a huge database in which to save all the information was created and a web management tool was designed and developed.”

Interviewer: “Do you plan to continue this research line?”
Marc: “As I said in the ‘future work’ section of my presentation, there are two different threads that will be followed: on the one hand, in my master thesis (TFM) I will enhance the management tool and work on the migration of data. On the other hand, data mining will be applied to the data in the database to extract implicit knowledge or patterns in the context of project Next-CBR, the continuation of MID-CBR. Therefore, I am going to continue this research line for some months in my TFM project although I still have to make a decision on what path to take afterwards.”

Many congratulations Marc and thank you for sharing this post with me!

What does the equation ZigBee + Cars = ZigBeeCars mean?

On March 19, ZigBeeCars will be presented in the Saló de l’ensenyament in view of promoting the engineering at La Salle. In a space of 35 square meters, offered by the EnginyCat program of the Generalitat de Catalunya, a spectacular racetrack will allow the public to drive seven cars at the same time through remote control from a PC. By means of this fun activity, many technical concepts could be brought to the students.

Further work of this project aims at incorporating AI to provide the cars with autonomy.

Hope you enjoy the activity!

 
 
 
 

Nowadays our society is worried about the decrease in the number of engineers and we do not understand why the profession that ten years ago was seen the job of the future, has not turned out to be so.

On the 22nd January, the program “Einstein a la platja” on BTV raised this question with experts who described the ideal engineer of the future, what skills should have, and how degrees should be adapted to recover vocational interest in engineering.

In a relaxed discussion, Ramon Ollé, president of the Business Engineering School La Salle, outlined a profession with more business concepts whereas Joan Amat, professor of Univeristat Politècnica de Catalunya, focused on technical abilities.

David E. Goldberg, professor of the University of Illinois, went one step further by proposing a social and entrepreneurial engineer. This new approach, with creativity as a backbone, highlights the importance of engineers in our society where they have moved from a secondary to a main role providing people with new and helpful devices aimed at making their lives easier and enjoyable.

 

CALL FOR PAPERS

The special session on Knowledge Extraction based on Evolutionary Learning in the 4th Hybrid Artificial Intelligent Systems (HAIS 2009) aims at bringing together researchers in Knowledge Extraction based on Evolutionary Learning to discuss new trends for the research in the field.

This special session intends to be a forum for researchers to exchange new ideas and present recent developments that address knowledge extraction processes by means of evolutionary algorithms.

 

We encourage authors to submit original papers as well as preliminary and promising works in the topics of the special session. You have until February 4, 2009 to submit your contribution.

See the CFP for more details.

Two weeks ago, one of the most important researchers in evolutionary computation visited the GRSI. After 25 years of an intense and extensive research on genetic algorithms, our guest, Prof. David E. Goldberg, focuses his interest on a new field, the entrepreneurship, where he displays his creativity to explore which non-technical skills an engineer should develop and how to adapt the training to attain these qualities. This new Prof. Goldberg’s passion leads him to write his latest book, entitled “The Entrepreneurial Engineer”. Some of his ideas are briefly presented in the Prof. Goldberg’s interview by “El Mundo”, in Spanish language.
 
 

 

Today, Núria Macià  and Rubén Nicolàs have set and explained the basis of their work. Please, join me in congratulating both Rubén and Núria as well as their supervisors Elisabet Golobardes and Ester Bernadó and in encouraging them to continue with their work. The following provides a view summary of the defenses.

DEA Ruben

Rubén’s DEA: At 11:00, Rubén started a nice talk on applying different types of learning algorithms, ranging from clustering techniques to CBR systems alike, to the detection of melanoma cancer. The talk was well developed and presented the hard work done on structuring the data and applying machine learning techniques to the problem. 

 

DEA NuriaNúria’s DEA: Thereafter, Núria started with a nice reflection on the need for characterizing our learning problems to fully capture the sources of difficulties and link them to the properties of different learning systems. With no doubt, this is an ancient goal stated in many fields (and further investigated in areas such as optimization) that was sort of overlooked in data classification but that needs to be addressed to advance in the current research of pattern recognition. The talk quickly shifted to the impressing contributions already provided by the thesis. Núria’s glancing back to some important lessons and pointing toward new promising research lines finished with the amazing talk.

 

Wrapping up: Many congrats Rubén and Núria!

Yesterday, Giovanni Pazienza received his PhD degree. The examining committee awarded the thesis and the presentation, entitled Aspects of algorithms and dynamics of cellular paradigms, with an Excellent Cum Laude. They also promised him a brilliant research career for his talent, dynamism, energy, and for many other of his qualities such as… “universality and fractality”.

Many congratulations and we hope you keep being persistent wherever you are!
 
 

On Friday 12, Albert Orriols received his PhD degree. He presented his work entitled New challenges in learning classifier systems: Mining rarities and evolving fuzzy models with a magnificent mise-en-scène which deserved the most sincere congratulations of the examining committee, especially from Prof. Goldberg who remarked that it was one of the best dissertation defenses he had attended.

To be honest, it was not a surprise, you had worked hard for that.

Many congrats!

The International Conference on Pattern Recognition finished last Thursday in Tampa, Florida. 1631 papers by 3556 authors from 47 countries were submitted of which 1006 were accepted and grouped into 74 regular and 16 poster sessions. In one of the latter, we found a work on synthetic data set generation based on a class separability measure, a little participation of the GRSI leaded by Núria Macià , Ester Bernadó-Mansilla, and Albert Orriols-Puig.
The poster session was great, many people from different places (Cuba, Italy, France, Germany, Russia, Spain, and United Kingdom) were interested in the work and provided us with helpful suggestions to improve and enlarge our framework. So, many thanks to all of them.

S+SSPR, a satellite event of the ICPR, took place last week in the hustle and bustle of the University of Central Florida in Orlando.

Dr. Tin Kam Ho did a talk at S+SSPR entitled Data complexity analysis: Linkage between context and solution in classification. She explained that classification accuracy depends on both learner quality and intrinsic data complexity. So, changes in source data and feature transformations are necessary to reduce the data difficulty and to improve learner performance. Among her collaborators, she mentioned the work performed by Ester Bernadó, Albert Orriols, and Núria Macià. Data complexity is a large knowledge area which should be explored in many directions, Dr. Ho suggested some of them for further research, easier to follow than the conference indications.

This picture was taken by Dr. Ludmila Kuncheva, another invited speaker. With some nice pictures and a fresh touch of humor, she presented Linear discriminant classifier (LDC) for streaming data with concept drift. She provided a framework within which theoretical relationship can be sought between the window size and the classification error.
She is also offering a promising lecture in the ICPR under the interesting title Classifier ensembles: Facts, fiction, faults and future.

Prof. Pedro Domingos presented an impressive work summarized by the title Markov logic: A unifying language for structural and statistical pattern recognition. It is a powerful language that combines statistical and structural aspects of the input data. Models in Markov logic are sets of weighted formulas in first-order logic which are interpreted as templates for features of Markov random fields.

Finally, Dr. Horst Bunke presented Graph classification on dissimilarity space embedding. He proposed a methodology that consists in embedding graphs in vector spaces and then applying a statistical classifier to outperform classifiers that directly operate in the graph domain. It is a contribution towards unifying the domains of structural and statistical pattern recognition. We highlight a graph data base repository that contains data sets covering a wide spectrum of different applications.

For further information, please refer to S+SSPR web site.

Prof. Chua

Anyone who ever took an electronics laboratory class will be familiar with the fundamental passive circuit elements: the resistor, the capacitor and the inductor. However, in 1971 Leon Chua reasoned from symmetry arguments that there should be a fourth fundamental element, which he called a memristor (short for memory resistor). Although he showed that such an element has many interesting and valuable circuit properties, until now no one has presented either a useful physical model or an example of a memristor. Here we show, using a simple analytical example, that memristance arises naturally in nanoscale systems in which solid-state electronic and ionic transport are coupled under an external bias voltage.

One application of the memristor could be to create a new type of ultradense non-volatile random access memory (RAM) that would supplement and eventually replace today’s commonly used dynamic random access memory (DRAM). Computers using conventional DRAM lack the ability to retain information once they lose power. When power is restored to a DRAM-based computer, a slow, energy-consuming “boot-up” process is necessary to retrieve data from a magnetic disk required to run the system. In contrast, a memristor-based computer would retain its information after losing power and would not require the boot-up process, resulting in the consumption of less power and wasted time.

Another potential application of memristor technology could be the development of computer systems that remember and associate series of events in a manner similar to the way a human brain recognizes patterns. This could substantially improve today’s facial recognition technology, enable security and privacy features that recognize a complex set of biometric features of an authorized person to access personal information, or enable an appliance to learn from experience.

Prof. Leon O. Chua will extensible talk about memristor in Enginyeria i Arquitectura La Salle on December 12 at 17:00. Go here to sign up for the talk.

Prof. David E. Goldberg will embark us in an interesting journey that starts considering simple GAs and follows the road to the design of competent GA, breaking the billion-variable optimization barrier. The talk will be held in Enginyeria i Arquitectura La Salle on December 11 at 18:00. Go here to sign up. In what follows, further information is provided.

Speaker: David E. Goldberg

Title: Not Your Grandmother’s Genetic Algorithm

Abstract: Genetic algorithms (GAs)–search procedures inspired by the mechanics of natural selection and genetics–have been increasingly applied across the spectrum of human endeavor. Genetic algorithms were also a primary ingredient in the rise in interest in the study of complex adaptive and emergent systems. Despite these salutary effects, some persist in thinking of evolutionary processes–and algorithms that rely upon them–as inherently slow, unreliable, and ad hoc, without much theoretical support. This talk briefly introduces GAs, but quickly shifts to a line of work that has succeeded in supporting GA mechanics with bounding design theory that has been used to demonstrate GA scalability, speed, and range of reliable applicability. Key elements of this theory are discussed to give insight into this accomplishment and to make the point that fast, scalable GAs may also be viewed as first-order models of human innovative or inventive processes. The talk highlights recent results in breaking the billion-variable optimization barrier for the first time. It also discusses recent experience with GA-inspired creativity or innovation support systems.

Title: The Creativity Imperative and the Technology Professional of the Future

Speaker: David E. Goldberg, Co-Director, Illinois Foundry for Innovation in Engineering Education

Abstract: The world (1) is apparently flat, (2) is being given over to a rising creative class, and (3) requires a whole new mind, but a common conclusion drawn from authors such as Friedman, Florida, and Pink is that technology professionals in advanced economies must excel at creating new categories of product and service, as returns to routine engineering/technology labor are declining because of the ease with which these tasks may be outsourced. This talk starts by examining the setting after World War 2 that has largely shaped engineering and technology education of the recent era. It continues by discussing the techno-economic forces that have affected the intervening time, and it considers recent work by Price in others to understand the essential characteristics and habits of tech visionaries (TVs) who currently help major companies create value through the effective bootstrapping of entirely new product lines. The talk concludes by discussing the newly established Illinois Foundry for Innovation in Engineering Education, including crucial organizational, content, and delivery innovations designed to promote effective and viral curriculum reform.

Pedraforca, magic mountain and symbol of Catalonia, offers wonderful views of the Bergadian countryside and further from its four peaks. On 5 October, Albert Orriols climbed this emblem to place at the top the abstract of his thesis and mark the end of his PhD student time.
The who, how, and more details of the adventure are found in the remainder of the article.

The party, composed of members of the GRSI, members of the lab, and Fí­gols (a lifelong friend of Albert), escorted the valued document to the top, the summary of four pleasant and intensive years of training and research, especially of the fourth (the hardest because one must finish off the work).

The climb took place in a peaceful setting under a blue and sunny sky and was divided into three stages.
A calm, easy walk led us to the “Refugi Lluí­s Estasen”, from where the courteous entourage saw us off.
Until the “Coll del Verdet”, all was joy, energy, and there were some difficulties but we managed to overcome them. At this second stop, some of the troop were a little bit tired so decided to head back to base but no before encouraging us to carry on, reviving the spirit of the five who were left to continue the mission.
At the top, with one of us exhausted (Núria), Albert, excited by the atmosphere, formalized the event with the signatures of those present on the abstract and left the sheet in a safe place. This year, on 31 December, the witches of Pedraforca will have a really interesting reading matter.

The rest of the day was spent at a barbecue at Albert’s home, where his parents treated us wonderfully. Thank you for your kind hospitality!

Finally, we can just say that this period for Albert will close with the thesis presentation on 12 December in front of an impressive examining committee: Prof. David E. Goldberg, Prof. Francisco Herrera, Prof. Martin Butz, Prof. Xavier Llorà, and Prof. Xavier Vilasís.

Good luck! It will not be an easy presentation (unlike the climb)!

The paper “Implementation of Traffic Engineering in NGNs Using Hybrid Genetic Algorithms” authored by Alex Vallejo, Agustín Zaballos, David Vernet, David Cutiller, and Jordi Dalmau won the best paper award the third International Conference on Systems and Networks Communications.

Many congrats Àlex, Agustí­n, David, and David!

Last Sunday, Loebner prize contest, the first instantiation of the Turing test, was held at Reading University, UK under the direction of Professor Kevin Warwick. What’s this all about? The challenge is to test whether a machine can imitiate human behavior, including their errors and their limited capacity to perform certain tasks.

To know more about the Turing test, the Loebner prize, and the challenges that AI is currently facing, listen to the interview here, where Giovanni Pazienza and Albert Orriols discuss about the contest and the research in the GRSI group.

Albert's Thesis AwardAlbert Fornells won the best thesis award for the thesis entitled “Marc integrador de les capacitats de Soft-Computing i de Knowledge Discovery dels Mapes Autoorganitzatius en el Raonament Basat en Casos”. The thesis presents a soft computing framework based on a case-based reasoning approach which integrates several soft computing mechanisms for prototype extraction and memory maintenance.

Many congrats Albert!

Congratulations and good job or in other words “Feliç sant Joan”

Albert in action

Xec Picture

Francesc Teixidó (Xec) is presenting his work on building picewise linear regressors from sets of continuously-labeled data with a hierarchical evolutionary algorithm. Fluent spanglish and nice, clear slides! And the best: today night celebration for the success :). Hope to see the follow-up of the work next year in Montreal!

Today’s agenda in GECCO: best paper nominees for GAs and EDAs. Therefore, going around to pick up some new ideas on enjoying nice discussions on several topics… and getting ready for tomorrow!

Still no pictures. But tomorrow, some labbies will be caught in action.

GECCO’08 has started with a fair enough amount of interesting tutorials and Workshops. Schedule for today: International Workshop on Learning Classifier Systems. Right now, we’ve seen very interesting papers on Pitts and Michigan LCS. Its seems that RL and knowledge representation is one of the most frequent topics dealt with in all the works.

Tomorrow: best paper awards sessions for EDAs and GA. So, stay tunned for more.

CALL FOR PAPERS
The special session on LCS: new Trends and Challenges in the 8th Hybrid Intelligent Systems Conference (HIS 2008) aims at bringing together researchers in Learning Classifier Systems (LCS) and Genetic-Based Machine Learning (GBML), with the interest of discussing recent and new perspectives for the research in the field. LCSs were introduced by John H. Holland as a way of applying evolutionary computation to machine learning problems. Since then, the LCS field has benefited from much research leading to competitive learners, with better theoretical support, and many applications. The special session aims to be a forum for researchers to discuss recent developments and future challenges of LCSs. We encourage authors to submit original papers as well as preliminary and promising works in the topics of the special session.
