A novel reinforcement learning architecture for continuous state and action spaces
We introduce a reinforcement learning architecture designed for problems with an infinite number of states, where each state can be seen as a vector of real numbers and with a finite number of actions, where each action ... -
An automatic algorithm for the detection of Trypanosoma cruzi parasites in blood sample images
Chagas disease is a tropical parasitic disease caused by the flagellate protozoan Trypanosomacruzi (T. cruzi) and currently affecting large portions of the Americas. One of the standard laboratory methods to determine the ... -

Chagas Parasite Detection in Blood Images Using AdaBoost
The Chagas disease is a potentially life-threatening illness caused by the protozoan parasite, Trypanosoma cruzi. Visual detection of such parasite through microscopic inspection is a tedious and time-consuming task. In ... -
Chagas Parasites Detection through Gaussian Discriminant Analysis
Visual detection of Chagas parasites through microscopic inspection is a tedious and time-consuming task. In this paper we provide an algorithm based on Gaussian discriminant analysis for the task of Chagas parasites ... -
Composition of Web Services Using Markov Decision Processes and Dynamic Programming
We propose a Markov decision process model for solving the Web service composition (WSC) problem. Iterative policy evaluation, value iteration, and policy iteration algorithms are used to experimentally validate our ... -
Corrección de errores del reconocedor de voz de Google usando métricas de distancia fonética
Los errores en los sistemas de reconocimiento de voz para el idioma español, como por ejemplo el de Google, ocurren con bastante frecuencia cuando se utilizan en aplicaciones de un dominio específico. Estos errores se ... -
Enfoque para la clasificación de vegetación polinífera usando imágenes multiespectrales y redes neuronales
La apicultura es una actividad pecuaria muy importante para México. Yucatán es uno de las entidades federativas que más aporta en producción y exportación de miel. Sin embargo, la apicultura se ve amenazada por una deficiente ... -
Geometría fractal en la superficie lunar
En este artículo se describe como la dimensión de Hausdorff-Besicovitch puede utilizarse para definir la dimensión fractal de un objeto y se muestra que dicha dimensión puede estimarse mediante el algoritmo de conteo de ... -
Image denoising using the Gaussian curvature of the image surface
A number of high-order variational models for image denoising have been proposed within the last few years. The main motivation behind these models is to fix problems such as the staircase effect and the loss of image ... -
Introducción a los métodos variacionales en procesamiento de imágenes: filtros de ruido
El cálculo variacional ha sido una herramienta matemática fundamental a lo largo de la historia. Muchos libros han sido dedicados a este tema pero son contados los que recientemente abordan técnicas variacionales para ... -
Mexican sign language alphanumerical gestures recognition using 3D haar-like features
The Mexican Sign Language (LSM) is a language of the deaf Mexican community, which consists of a series of gestural signs articulated by hands and accompanied with facialexpressions. The lack of automated systems ... -

Usability evaluation of an augmented reality system for teaching Euclidean vectors
Augmented reality (AR) is one of the emerging technologies that has demonstrated to be an efficient technological tool to enhance learning techniques. In this paper, we describe the development and evaluation of an AR ... -
Use of classification algorithms for semantic Web services discovery
Web services (WS) are used in different environments like enterprises, government and industry, providing tools for implementing complex distributed systems. Web service discovery allows a system to find services that meet ... -
Web service composition using the bidirectional Dijkstra algorithm
Web services are not always able to fulfill customer requirements on their own, so in those cases it can choose to make a composition of web services. However, this is a complex problem since it must take into account the ...
