Regresion PLS y PCA como Solucion al Problema de Multicolinealidad en Regresion Multiple
Regresion PLS y PCA Como Solución al Problema de Multicolinealidad en Regresion Multiple 

Vega Vilca, José Carlos; Guzman, Josué (2011-03-18)
We present and compare principal components regression and partial least squares regression, and their solution to the problem of multicollinearity. We illustrate the use of both techniques, and demonstrate the superiority ...

Creation of a Model of Pollutans Diffusion in Soil-Water System Using a Cellular Automata
Uso de un Autómata Celular para Crear un Modelo de Difusión de Contaminantes en un Sistema Suelo–Agua 

Merino Castro, Glicina (2011-03-18)
In this paper is presented a developed model for a pollutant diffusion in a soil-water system, for specific conditions in a real study area. A model that allows the observations of the pollutant flow in the soil-water ...

Heuristics for the Robust Coloring Problem
Heurísticas para el Problema de Coloracion Robusta 

Gutiérrez Andrade, Miguel Ángel; Lara Velázquez, Pedro; Lopez Bracho, Rafael; Ramírez Rodríguez, Javier (2011-03-18)
Let $G$ and $\bar{G}$ be complementary graphs. Given a penalty function defined on the edges of $G$, we will say that the rigidity of a $k$-coloring of $G$ is the sum of the penalties of the edges of G joining vertices of ...

Curvas ROC y Vecinos Cercanos, Propuesta de un Nuevo Algoritmo de Condensación
Curvas ROC y Vecinos Cercanos, Propuesta de un Nuevo Algoritmo de Condensación 

Jiménez Padilla, Raquel; Cuevas Covarrubias, Carlos (2011-03-18)
k-NN criteria are non parametric methods of statistical classificaction. They are accurate, versatile and distribution free. However,  their computational cost may be too expensive; especially for large sample sizes. We ...

A Non-Standard Generating Function for Continuous Dual q-Hahn polynomials
Una Función Generatriz no Estandar para Polinomios q-Hahn Duales Continuos 

Atakishiyeva, Mesuma; Atakishiyev, Natig (2011-03-18)
We study a non-standard form of generating function for the three-parameter continuous dual q-Hahn polynomials $p_{n} (x; a, b, | q)$, which has surfaced in a recent work of the present authors on the construction of lifting ...

Heuristics for Solving the Multiple Problem Identification of the Responses of Brain and Artificial Neural Networks in the Presence of Usual and Unusual Stimuli by Means of Kalman-Type Filters
Identificación de las Respuestas de Redes Neuronales Cerebrales y Artificiales ante la Presencia de Estímulos Frecuentes e Infrecuentes mediante Filtros de tipo Kalman 

Cardo, Romina; Corvalán, Alvaro (2011-03-18)
We consider the problem of obtaining information about the recognition of logical inconsistencies with already imprinted patterns of a subnetwork of a neural network, both cerebral and artificially designed, by means of ...

Integral Equations for the Aggregate Claim Amount
Ecuaciones Integrales para el Monto Agregado de Reclamaciones 

Pacheco González, Carlos G. (2011-03-18)
In the context of insurance mathematics, we study the renewal properties of the so-called aggregate claim amount for the non-discounted and the discounted case. For these models, we set integral equations for the distribution ...
