In this work the risk-sensitive optimal filtering equations for systems of third grade with linear observations and mean square cost criterion to be minimized had been applied to the Fitz Hugh-Nagumo model. This special model represents a excitable system. The performance of the obtained risk-sensitive estimator for third degree stochastic systems with polynomial linear drift terms with polynomial observations equations is verified, comparing the mean-square criteria values in final time for the optimal risk-sensitive estimator and polynomial filtering equations. The goal of this work is to experiment applying both filtering equations: risk-sensitive and polynomial to third degree polynomial systems, comparing the results obtained in this special model. It is observed that when the value of D is greater than 1, the risk-sensitive equations present a singularity. However, the estimates are better than the polynomial filtering equations with respect to the values of the proposed mean square cost criterion to be minimized.
Los sistemas de inferencia difusos se utilizan para el análisis de decisiones o reconocimiento de patrones con el propósito de ayudar a tomar elecciones como lo haría un experto en el área. En esta investigación se desarrolló e implementó un sistema en un juego serio que ayuda a fortalecer el razonamiento lógico-matemático, el sistema evalúa si el alumno avanza, regresa o se queda en el mismo nivel con base en el tiempo y los aciertos de cada misión. Los resultados muestran que los estudiantes que avanzaron por lo menos al siguiente nivel mejoraron a diferencia de los que no.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
