Dentro del CEDI está teniendo lugar estos días el MAEB2010.

En la sesión de Algoritmos Evolutivos acabo de presentar (hace unos minutos) el trabajo “Optimizando la implementación de algoritmos evolutivos”.

Os dejo la presentación que he hecho:

CEC 2010: Evolving Natural Language Grammars without Supervision

Filed under: Uncategorized — lurdesaraujo @ 8:57 am

Another work presented world congress on computational intelligence has been: Evolving Natural Language Grammars without Supervision. paper: Training a Classifier for Good Query Expansion Terms with a Genetic Algorithm.

This work is devoted to unsupervised grammar induction, whose goal is to extract a grammar representing the language structure using texts without annotations of this structure. We have devised an evolutionary algorithm which for each sentence evolves a population of trees that represent different parse trees of that sentence. Each of these trees represent a part of a grammar.
The evaluation function takes into account the contexts in which each sequence of Part-Of-Speech tags (POSseq) appears in the training corpus, as well as the frequencies of those POSseqs and contexts.
The algorithm has been evaluated using a well known Annotated English corpus, though the annotation have only been used for evaluation purposes. Results indicate that the proposed algorithm is able to improve
the results of a classical optimization algorithm, such as EM (Expectation Maximization), for short
grammar constituents (right side of the grammar rules), and its precision is better in general.

Fluid Evolutionary Algorithms at WCCI’2010

Filed under: Uncategorized — Tags: , , — jjmerelo @ 5:04 pm

We are freshly back from the world congress on computational intelligence, and papers do not seem to be available yet. However, our presentations are. This is a paper on Fluid Evolutionary Algorithms, basically figuring out how a more or less traditional EA could be implemented over the new FluidDB, a database with the spirit of a wiki.

The paper is not available yet at IEEEExplore, but we can email to whoever is interested.

El proyecto NoHNES es un proyecto interdisciplinar financiado por el MICINN con el código TIN2007-68083. Tiene dos subproyectos, uno en la Universidad de Granada y otro en el Instituto Tecnológico de Informática en la Universidad Politécnica de Valencia, pero en torno a esos dos nodos se agrupan investigadores de más de media docena de universidades.

El principal objetivo del proyecto es la investigación de algoritmos evolutivos y bioinspirados, principalmente en un entorno de computación distribuida.
