\nNota técnica: Se utilizaron datos de todos los estudiantes chilenos egresados de IV Medio en 2016 (fuente: MINEDUC). Se entrenó una red neuronal de múltiples capas (deep learning) con los datos de Comuna, Dependencia y Nivel de Rendimiento para clasificar a los estudiantes en las distintas Instituciones de Educación Superior a la que se matricularon en 2017 (o ninguna si es el caso).\nDesarrollado por en el Laboratorio de Innovación de TIDE SA (www.tide.cl)\n
