Generación de métricas en análisis de datos
(2009-02-20)In this work we introduce primary generators of metrics, that consist of linearcombinations of known metrics. We establish some theoretical properties of these generators,related to the computation of principal components, ... -
Generación de reglas estadísticas a partir de grandes bases de datos
(2009-02-18)Given a set of categorical variables, we want to predict one or more of them by the way rules. We propose an algorithm that (i) is guided by statistical results in a relational geometry where we use assymetrical association ... -
Generadores de números primos y factorizadores de números compuestos
(2009-02-20)The sequence of natural numbers presents itself as a multidimensional array. Twoproblems are solved on the basis of these arrays:a) distribution of prime numbers in multidimensional array,b) factoring of composite numbers.For ... -
General guidelines solution for linear programming with fuzzy coefficients
(2013-08-29)This work introduce to the Possibilistic Programming and the Fuzzy Programming as paradigms that allow to resolve problems of linear programming when the coefficients of the model or the restrictions on the same are presented ... -
Generalización a Rn de algunos métodos de interpolación conocidos en ecuaciones diferenciales
(2009-02-18)We present the Runge-Kutta methods of several one-step levels in Rn , as well as algorithms in pseudo-code for the implicit and explicit methods. We study the problem of error control in Rn and we give numerical examples ... -
Generalización de dos métodos de detección de conglomerados. Aplicaciones en bioinformática.
(2009-02-25)This paper presents a modification to the temporal disease clusters methods inorder to apply them to other sciences. Particular specifications are shown in Scanand temporal Grimson techniques. The original data are transformed ... -
Generalization of Rakotch's fixed Point Theorem
(2011-04-29)In this paper we get some generalizations of Rakotch's results [10] using the notion of $\omega ?distancia$ on a metric space -
GEODESIC DISTRIBUTION IN GRAPH THEORY: KULLBACK-LEIBLER-SYMMETRIC
(2014-07-01)Kullback-Leibler information allow us to characterize a family of dis- tributions denominated Kullback-Leibler-Symmetric, which are distance functions and, under some restrictions, generate the Jensen’s equality shown by ... -
Geostatistical Spatio-Time model of crime in el Salvador: Structural and Predictive Analysis
(2011-07-26)Today, to study a geospatial and spatio-temporal phenomena requires searching statistical tools that enable the analysis of the dependency of space, time and interactions. The science that studies this kind of subjects is ... -
GNM-NIPALS: general nonmetric-nonlinear estimation by iterative partial least squares
(2014-04-03)This paper develops GNM-NIPALS as an extension of the NM-PLS methods, which allows to quantify the qualitative variables of mixed data, by means of the reconstitution function using the first k principal com- ponents, ... -
Goal problems in gambling theory
(2009-02-18)A short introduction to goal problems in abstract gambling theory is given, along with statementes of some of the main theorems and a number of examples, open problems and references. Emphasis is on the finite-state, ... -
Grafos destinados al Análisis de datos Multivariante Condicionado por su Estructura
(2012-04-26)We present two new methods for the construction of graphs that can be used with descriptive techniques of Multivariate Data Analysis: a graph based in the chi-square distance and a graph based in strongly-connected components. ... -
Graph dominance by rook domains for Znp and Zn3 × Zm2 graphs
(2009-02-20)Described within is the problem of finding near-minimum dominating subsets of agiven graph by rook domains. Specifically, we study the graphs of the kind ZnpandZn3×Zm2and introduce a simulated annealing algorithm to compute ... -
Herramientas matemáticas para la valoración de la ampliación de una infraestructura portuaria
(2009-02-20)infraestructuraportuaria ya consolidada, que conlleva unas inversiones a largo plazo.Para ello hay que recurrir a medios de an´alisis capaces de recoger, en la medidade lo posible, la incertidumbre sobre la futura evoluci´on ... -
Heuristic analysis of a near optimal approximation algorithm for the determination of investment options
(2009-02-20)When cash becomes available in a company, there are several strategies that allowus to benefit from it. The problem is how much to invest, for how long, and using whichof the investment options in order to get the maximum ... -
Heuristic for Solving the Multiple Alignment Sequence Problem
(2011-03-18)In this paper we developed a new algorithm for solving the problem of multiple sequence alignment (AM S), which is a hybrid metaheuristic based on harmony search and simulated annealing. The hybrid was validated with the ... -
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
(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 ... -
Heuristics for the Robust Coloring Problem
(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 ... -
