Semi-supervised document classification using ontologies 

Aparicio-Carrasco, Roxana K. (2011)
Many modern applications of automatic document classification require learning accurately with little training data. Addressing the need to reduce the manual labeling process, the semi-supervised classification technique ...

Clasificación noparamétrica en datos direccionales 

Velasco-Forero, Santiago A. (2004)
In a supervised classification problem, when the vectors of data are direction- al, it means, that they take values on a k-dimensional sphere, the application of the algorithms of pattern recognition as k-nearest-neighbour ...

Clasificadores por redes bayesianas 

López de Castilla-Vásquez, Carlos (2005)
A Bayesian network is a compact representation of joint probability function. Formally, a Bayesian network is an acyclic directed graph in which each node represents a random variable and the relationships of dependence ...

Estimación de densidades multivariadas en flujo de datos usando mezclas adaptativas de componentes gaussianas 

Moyano-Niño, Héctor (2012-06)
In the current world of science and technology the data arrive continuously over time, this type of data is called data stream and is impractical to store all of the data. The data mining and traditional techniques of ...

Algorithms for non-parametric classifiers in multi-relational data mining 

Encarnación-Rivera, Trilce M. (2006)
Over the last decades, due to the advances in information technologies, both the industrial and scientific communities have acquired large volumes of data in digital form. Most of these data sets are stored using relational ...

Generalizaciones de minimos cuadrados parciales con aplicación en clasificacion supervisada  

Vega-Vilca, Jose C. (2004)
The development of technologies such as microarrays has generated a large amount of data. The main characteristic of this kind of data it is the large number of predictors (genes) and few observations (experiments). Thus, ...

A comparison in cluster validation techniques 

González-Toledo, Marggie D. (2004)
Clustering may be defined as a process that aims to find partitions of similar objects. It is an unsupervised recognition procedure since there are no predefined classes that indicate grouping properties in the data set. ...
