Laboratorio de Información y Decisión (Information and Decision Systems Group, IDS)

Descripción

El interés central de la iniciativa IDS son los problemas inversos en presencia de incertidumbres que puedan plantearse como instancias de tareas de decisión y estimación.

El grupo trabaja activamente tanto en investigación aplicada como en el desarrollo de nuevos métodos y resultados teóricos.

Lo integran  tres académicos con formación y experiencia demostrada en temas de estimación y decisión, teoría de información y aprendizaje estadístico, filtrado y predicción, procesamiento de señales, diseño de dispositivos y sensores.
