Claim 23:
24. A non-transitory computer-readable medium having contents which configure processing circuitry including neural network classification circuitry to perform a method, the method comprising:
generating, using a user-activity classification model including a set of classifier model parameters, a set of raw predictions based on inertial sensor data; and
generating one or more control signals to control a user interface based on the set of raw predictions, wherein the generating the set of raw predictions includes:
applying to said raw predictions temporal filtering and heuristic filtering, producing filtered predictions;
generating a prediction error from said filtered predictions; and
updating model parameters of said set of classifier model parameters based on said prediction error; wherein

said heuristic filtering includes selecting transitions between a source class and a destination class for which a number of predictions of the destination class reaching a confirmation threshold have been detected over a temporal window,
the temporal window has a defined duration, and
the confirmation threshold is a threshold number of predictions.
