  • Publication number: 20240070232
    Abstract: Methods and systems for training a model include determining class prototypes of time series samples from a training dataset. A task corresponding to the time series samples is encoded using the class prototypes and a task-level configuration. A likelihood value is determined based on outputs of a time series density model, a task-class distance from a task embedding model, and a task density model. Parameters of the time series density model, the task embedding model, and the task density model are adjusted responsive to the likelihood value.

  • Publication number: 20240064399
    Abstract: The present disclosure relates to automatic user adaptive triggering, such as triggering of always-on vision. A camera may be activated based on a result of applying a set of sensor features to a logic model. A label for the set of sensor features may be determined based on whether a face is detected or a face is not detected in a first set of images captured by the camera. The labeled sensor data may be stored along with historical data. A user behavior model may be generated using a learning algorithm based on the labeled sensor data. The user model may be incrementally updated based on new training data. The user behavior model may be used for determining whether to the activate the camera based on a particular set of sensor features.
