    Plan recognition as planning 

    Ramírez Jávega, Miquel (Date of defense: 2012-05-17)

    Plan recognition is the problem of inferring the goals and plans of an agent after partially observing its behavior. This is the inverse of planning, the problem of finding the actions that need to be done in order to ...

    Prediction-based strategies for reducing data transmissions in the loT 

    Martins Dias, Gabriel (Date of defense: 2016-10-28)
