A first study on the use of interval-valued fuzzy sets with genetic tuning for classification with imbalanced data sets
(Springer, 2009)
Contribución a congreso / Biltzarrerako ekarpena,
Classification with imbalanced data-sets is one of the recent
challenging problems in Data Mining. In this framework, the class dis-
tribution is not uniform and the separability between the classes is often
difficult. ...
Adjusting fuzzy automata for string similarity measuring
(EUSFLAT, 2001)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we introduce a fuzzy
automaton for computing the similarity
between pairs of strings and a genetic
method for adjusting its parameters.
The fuzzy automaton models the
edit operations needed to transform ...
On fuzzy orderings of crisp and fuzzy intervals
(EUSFLAT, 2001)
Contribución a congreso / Biltzarrerako ekarpena,
First, fuzzy membership functions for the assertion '[x,y] is a positive interval' are proposed and
characterized via non-decreasing real maps. Last, using those functions together with the intervaldifference
and the ...
Mejoras en la identificación de tráfico de aplicación basado en firmas
(2008)
info:eu-repo/semantics/conferenceObject,
Traffic identification has been based traditionally on transport protocol ports, associating always the same ports with the same applications. Nowadays that assumption is not true and new methods like signature identification ...
Collecting packet traces at high speed
(2006)
info:eu-repo/semantics/conferenceObject,
In order to capture packet traces at high speed using a
low-cost platform, we have to optimize the networking stack of a
general purpose operating system. Different techniques are
compared with the final objective of ...
Internet mapping at IP level
(2009)
info:eu-repo/semantics/conferenceObject,
The final objective of our research is to develop new techniques and ideas to create topology maps at IP level, representing Internet as a graph where nodes were routes. This means closer to reality.
Predicción de tráfico de Internet and aplicaciones
(2001)
info:eu-repo/semantics/conferenceObject,
In this paper we focus on traffic prediction as a means to achieve dynamic bandwidth allocation in a generic Internet link. Our findings show that coarse prediction (bytes per interval) proves advantageous to perform dynamic ...
A-priori flow bandwidth estimates for dynamic bandwidth allocation in ISP access links
(2001)
info:eu-repo/semantics/conferenceObject,
In this paper we study a-priori bandwidth estimation algorithms for TCP flows. An RTT-based
bandwidth allocator is proposed, which outperforms a broad class of peak-rate and static allocation
flow switching solutions. Our ...
On linear prediction of Internet traffic for packet and burst switching networks
(IEEE, 2001)
info:eu-repo/semantics/conferenceObject,
In this paper, we show that prediction algorithms in the least
mean square error sense prove better in a burst rather than in a packet
switching network. For the latter, further information about the packet
arrival ...
Characterizing Internet load as a non-regular multiplex of TCP streams
(IEEE, 2000)
info:eu-repo/semantics/conferenceObject,
A commonly accepted traffic model for a large population of Internet users consists of a multiplex of Poisson-arriving heavy-tailed streams with the same constant rate (M/G//spl infin/). We show that even though such a ...
