1. A method of generating a classification indicator on an electronic device based on a predictive model, the electronic device comprising a device-sensor group for sensing data related to an environment of the electronic device, the method comprising: generating one or more respective weight vector coefficients for one or more support vectors of the predictive model on a computing device remote from the electronic device; storing the predictive model including the one or more respective weight vector coefficients but excluding the support vectors on the electronic device; running the predictive model on the electronic device based on the weight vector coefficients and input received from the device-sensor group; generating a classification decision based on running the predictive model; and generating a classification indicator to modify a behavior of the electronic device.
