Abstract
Disclosed are systems, methods, and apparatus for unsupervised training of an activity classifier for movement measured at a target location of a user using a trained source activity classifier configured to determine an activity based on motion measured at a source location of a user. According to exemplary embodiments, the activity classifier for the target location can be trained using source embeddings generated by a trained classifier for the source location. For example, the source embeddings and the motion measured at the target location may then be provided as training inputs to the target activity classifier for the target location of a user, so that the target activity classifier can reconstruct the source embedding for the target motion without the use of any labeled training data and/or without having to learn the transfer function of the existing trained machine learning model.
