Clustering binary data by application of combinatorial optimization heuristics
We study clustering methods for binary data, first defining aggregation criteria that measure the compactness of clusters. Five new and original methods are introduced, using neighborhoods and population behavior combinatorial ...
Estimación de población contagiada por Covid-19 usando regresión Logística generalizada y heurísticas de optimización
En este trabajos se presenta una propuesta para la estimación de la poblaciones usando ajuste de curvas del tipo logística. Este tipo de curvas se utilizan para el estudio de crecimiento de poblaciones, en este casos ...
Zilber's Dichotomy for Differentially Closed Fields with an Automorphism
The theory of difference-differential fields of characteristic zero hasa model-companion denoted byDCFA. In  we prove its main properties. In we proved a weak version of Zilber’s dichotomy forDCFA. In this paperwe ...
A Geometric Splitting Theorem
Let G = G1...Gl be a connected noncompact semisimple Lie group with Lie algebra g = g_1+g_2+....+ g_l acting topologically transitive on a manifold M. We obtain a geometric splitting of the metric on M that consider ...
Definable Additive Subgroups of Partial Differential Fields of Characteristic Zero with an Automorphism
Abstract.The theory of partial differential fields of characteristic zero withan automorphism has a model companion denoted DCFmA. This theory isnot complete, but its completions are easily discribed. They are supersimpleand ...
Using generalized logistics regression to forecast population infected by Covid-19
In this work, a proposal to forecast the populations using generalized logistics regression curve fitting is presented. This type of curve is used to study population growth, in this case population of people infected ...
