1. A system for the prediction of a user goal for command/control of a personal device, comprising:

  • a user data store that stores information regarding a particular user'"'"'s behavior with respect to the personal device;

    a predictive user model that receives a user input and employs statistical modeling of the information stored in the user data store to predict a command/control, based at least in part on a past pattern of behavior by the user, to be automatically performed by the personal device; and

    an execution component that automatically performs the command/control determined according to the predictive user model,wherein at least one of a parameter and a structure of the predictive model is updated in an online manner, andwherein the online update is performed according to a learning rate (β

    ), wherein the learning rate is;
