Treball Final de Grau
Accés obert
Realitzat a/amb: Univerzita KarlovaLa coloració de grafs dibuixats a superfícies és un àrea antiga i molt estudiada de la teoria de grafs. Thomassen va demostrar que hi ha un nombre finit de grafs 6-crítics a qualsevol superfície fixa i va proporcionar el ... -
A constraint-based hypergraph partitioning approach to coreference resolution
(Universitat Politècnica de Catalunya, 2012-05-16)
Tesi
Accés obertThe objectives of this thesis are focused on research in machine learning for coreference resolution. Coreference resolution is a natural language processing task that consists of determining the expressions in a discourse ... -
A contribution on adaptive coding strategies over H.F. channels
(1989)
Text en actes de congrés
Accés obertWe present a coding scheme which makes use of adaptive coding techniques. Since we are concerned with the H,F, channel, suitable coding schemes are needed to combat diffuse errors [1], i. e, random and burst errors, ... -

Article
Accés obertAn evolutionary algorithm formalism has been forwarded in a previous research, and implemented in the system GIGANTEC: Genetic Induction for General Analytical Non-numeric Task Evolution Compiler [Bad98][Bad99]. A dynamical ... -
A general adaptive algorithm for nonGaussian source separation without any constraint
(1994)
Text en actes de congrés
Accés obertThis paper deals with the blind source separation. The task consists in separating some independent and linearly mixed signals called sources. After some general remarks, the model is recalled and our approach based on the ... -
A genetic algorithm for the mixed flow shop problem
