Research Professor Position in Big Data at UNAM

The Computer Science Department of the Instituto de Investigaciones en Matemáticas Aplicadas y en Sistemas (IIMAS) of the Universidad Nacional Autónoma de México (UNAM) has a open call for a research professor in big data. This position, aimed at young researchers, consists of renewable one-year contracts with the possibility of tenure after three years.

Located in the heart of the UNAM's Ciudad Universitaria, a UNESCO World Heritage site, the IIMAS has been the leader in computer science in Mexico since the first computer in the country was acquired by UNAM. Researchers at UNAM have a privileged position for several reasons. UNAM is the highest ranked spanish speaking higher education institution in the world and produces half of the research in Mexico and is the largest in the continent (300K+ students). Professors in faculties do more teaching than research, while researchers in institutes (such as IIMAS) do more research than teaching (about 48 hours per year, usually to the best graduate students in the country. Groups of more than five students get a teaching assistant). Students in most graduate programs at UNAM receive automatically a scholarship, and there is travel budget for researchers, minimizing the grant writing load. There are several grant calls with high acceptance rates. There are also two postdoctoral fellowship calls per year internal to UNAM. High performing researchers can reach tenure in less than five years.

Requirements for this call are:

  1. To be less than 39 (women) or 37 (men) years old.
  2. To have a PhD degree in computer science or related fields from a renowned institution.
  3. To have published high quality research papers related to big data.
  4. To have teaching skills at undergraduate and graduate levels.
  5. To have abilities to direct undergraduate and graduate theses.
  6. To be able to collaborate in multidisciplinary research projects.
  7. To fulfill the norms described at http://dgapa.unam.mx/html/sija/sija.html
Interested candidates should send the following documentation to Dr. Ricardo Berlanga (berlanga "at" unam.mx), Academic Secretary of IIMAS before October 7th, 2014:
  1. Application request (in Spanish).
  2. Updated Curriculum Vitae, including publication list (in Spanish).
  3. Copy of PhD degree.
  4. Copy of publications.
  5. At least two references with email included.
  6. A work plan which includes research and teaching prospects for the next three years (in Spanish.
Selected candidates will be invited to give an open talk or videoconference at IIMAS. An ad hoc commission will make a final decision.

More information can be requested to:
Dr. Carlos Gershenson
Head of Computer Science Department, IIMAS, UNAM

New Essay Published: Harnessing the complexity of education with information technology

Education at all levels is facing several challenges in most countries [1-4], such as low quality, high costs, lack of educators, and unsatisfied student demand. Traditional approaches are becoming unable to deliver the required education. Several causes for this inefficiency can be identified. I argue that beyond specific causes, the lack of effective education is related to complexity [5, 6]. However, information technology is helping us overcome this complexity.
Complexity can be measured with information theory and can be seen as the balance between stability and variability [7-10]: phenomena without change or with constant change cannot exhibit complex behavior. It has been noted that to actively control a complex system, the controller has to be at least as complex as the controlled [11, 12]. For example, a successful healthcare provider has to match the complexity of the patients she attends. Treatment is highly specific for different patients, so a general practitioner must have a high complexity to attend patients with diverse conditions. Concerning most preventive services, these are similar for most patients, and thus, can be delivered efficiently by providers with a lower complexity [13]. A similar approach can be used to study education and its complexity: a successful educational system has to match the complexity of its students.

Paper published: Measuring the Complexity of Self-Organizing Traffic Lights

We apply measures of complexity, emergence, and self-organization to an urban traffic model for comparing a traditional traffic-light coordination method with a self-organizing method in two scenarios: cyclic boundaries and non-orientable boundaries. We show that the measures are useful to identify and characterize different dynamical phases. It becomes clear that different operation regimes are required for different traffic demands. Thus, not only is traffic a non-stationary problem, requiring controllers to adapt constantly; controllers must also change drastically the complexity of their behavior depending on the demand. Based on our measures and extending Ashby’s law of requisite variety, we can say that the self-organizing method achieves an adaptability level comparable to that of a living system.

Paper published: Complexity measurement of natural and artificial languages

We compared entropy for texts written in natural languages (English, Spanish) and artificial languages (computer software) based on a simple expression for the entropy as a function of message length and specific word diversity. Code text written in artificial languages showed higher entropy than text of similar length expressed in natural languages. Spanish texts exhibit more symbolic diversity than English ones. Results showed that algorithms based on complexity measures differentiate artificial from natural languages, and that text analysis based on complexity measures allows the unveiling of important aspects of their nature. We propose specific expressions to examine entropy related aspects of tests and estimate the values of entropy, emergence, self-organization, and complexity based on specific diversity and message length.

Commentary published: Info-computationalism or Materialism? Neither and Both

Upshot: The limitations of materialism for studying cognition have motivated alternative epistemologies based on information and computation. I argue that these alternatives are also inherently limited and that these limits can only be overcome by considering materialism, info-computationalism, and cognition at the same time.

Call for Abstracts: Design and Control of Self-organising Systems @ WOSC 2014

The 16th International Congress of Systems and Cybernetics WOSC2014 will take place on October 15-17 a the University of Ibagué, Colombia.

One of the congress themes is Design and Control of Self-organising Systems

Many real-world problems are non-stationary and highly complex. That is, they are changing constantly and interacting, generating novel information that limits prediction. If the change is faster than our ability to optimize our solutions, then these will be obsolete. As an alternative, we have designed adaptive systems, in many cases inspired in biology. One approach for designing adaptive systems has been proposed with the use of self-organization: instead of trying to optimize a problem, the aim is to design components of a system that by local interactions actively search for their best configuration. When designed properly, self-organizing systems can adapt to extremely dynamic and complex problems at the same scales at which changes occur. As our systems become more dynamic and complex, designing them using self-organization offers greater benefits compared with traditional approaches.

Calls for abstract submissions are open until March 31st 2014.
Submitters will be notified of acceptance or rejection no later than April 30th.
