Variables latentes para identificar el infarto agudo del miocardio mediante análisis de componentes principales probabilístico
Abstract
Este articulo presenta algunos resultado parciales de una reciente investigación [1] que comparó varias técnicas lineales y no lineales del análisis multivariado de datos con el objeto de seleccionar y extraer de manera efectiva un grupo de características basadas en señales electrocardiográficas orientadas a la identificación del infarto agudo de miocardio. Específicamente en este artículo se presentan los resultados obtenidos al aplicar el Análisis de Componentes Principales Probabilístico (Probabilistic Principal Component Analysis- PPCA) para generar un subespacio de características de menor dimensión que el original. Se presentan también los resultados obtenidos al evaluar la precisión de la clasificación de estados funcionales normales y patológicos del miocardio utilizando un clasificador bayesiano. Además, se estimó también su costo computacional.Downloads
