On local times, density estimation and supervised classification from functional data
(Elsevier Inc, 2011-01)
In this paper, we define a n-consistent nonparametric estimator for the marginal density function of an order one stationary process built up from a sample of i.i.d continuous time trajectories. Under mild conditions we ...
Pattern recognition via projection – based k – NN rules
(Universidad de San Andrés. Departamento de Matemáticas y Ciencias, 2008-06)
We introduce a new procedure for pattern recognition, based on the concepts of random projections and nearest neighbors. It can be thought as an improvement of the classical nearest neighbors classification rules. Besides ...
Técnicas de machine learning aplicadas no processo de certificação de granjas avícolas
(Universidade Federal de Santa MariaBrasilUFSMColégio Politécnico da UFSM, 2023-07-04)
In recent years, the field of Artificial Intelligence (AI) has shown many advances, especially with the use of machine learning and neural networks, generating great research opportunities. A large part of the expansion ...
Nuevos métodos de selección de objetos y su aplicación sinérgica
(Instituto Nacional de Astrofísica, Óptica y Electrónica, 2007)
Heurística inspirada en el análisis sistémico del “Vecino más cercano”, para solucionar instancias simétricas TSP, empleando una base comparativa multicriterio
(2011)
Esta tesis aporta evidencia que respalda al pensamiento sistémico como un pertinente campo de inspiración para el desarrollo de nuevos métodos de optimización heurística. Se delimita el alcance a la resolución del TSP ...
A sensor data fusion system based on k-Nearest neighbor pattern classification for structural health monitoring applications
(2017-02-21)
Civil and military structures are susceptible and vulnerable to damage due to the
environmental and operational conditions. Therefore, the implementation of technology to provide
robust solutions in damage identification ...

Time series classification with motifs and characteristics
(Springer-VerlagHeidelberg, 2014)
In the last years, there is a huge increase of interest in application of time series. Virtually all human endeavors create time-oriented data, and the Data Mining community has proposed a large number of approaches to ...
The mass media destabilizes the cultural homogenous regime in Axelrod`s model
(IOP PUBLISHING LTD, 2010)
An important feature of Axelrod`s model for culture dissemination or social influence is the emergence of many multicultural absorbing states, despite the fact that the local rules that specify the agents interactions are ...
Competing and aperiodic interactions in the Ising chain
(1997)
We investigate the effects of the inclusion of aperiodic interactions in the Ising chain with competing ferro and antiferromagnetic couplings between nearest and next-nearest-neighbor sites. In particular, we obtain the ...
