Difusión y Transferencia


In terms of research, we pay a special effort to face AI from a multidisciplinary perspective by applying machine learning techniques to different application areas. In particular, we face research challenges to develop and scale new machine learning techniques to the case of large data problems in fields such as: bioinformatics [1], astronomy [2], food quality evaluation [3], and computer vision [4]. We strongly believe that besides scaling machine learning techniques to big data scenarios it is also highly relevant to establish a close connection to the application areas.

    DIARIO EL MERCURIO

    Chile, 2018

    El Premio de Innovación Avonni es el reconocimiento honorífico más importante de Chile, que busca visibilizar los casos de éxito que están creando valor mediante la innovación en distintos rubros y categorías. Este premio fue otorgado a la empresa Zippedi, co-fundada y liderada por el profesor del Departamento de Ciencias de la Computación, Álvaro Soto. Este importante reconocimiento fue logrado por la creación del primer robot chileno con inteligencia artificial que entrega servicios a la industria del retail, siendo capaz de monitorear errores en los rótulos de los precios y detectar productos mal ubicados en las góndolas de supermercados.
