1. A hearing instrument comprising:
a memory configured to store a plurality of machine trained activity models, each of the machine trained activity models corresponding to a respective type of activity; and
at least one processor configured to:
determine, by applying a hierarchy of the plurality of machine trained activity models to motion data indicative of motion of the hearing instrument, a type of activity performed by a user of the hearing instrument, wherein the machine trained activity models are ranked within the hierarchy by probabilities of the user performing the respective types of activities corresponding to the machine trained activity models; and
responsive to determining the type of activity performed by the user, output data indicating the type of activity performed by the user.
