A computer-implemented method and system are provided for controlling operation of one or more electronic devices based on detection of a meaningful context change in context data describing a human experience. Context data, including aspects such as actions and intents, is received from one or more devices and used to predict subsequent actions and intents associated with a task. A distributional representation generates latent states corresponding to the predicted aspects, and a predictor estimates next latent states. A comparison between predicted and actual latent states yields a distance metric used to identify a meaningful context change. The method distinguishes temporary variations from changes requiring adaptation of a machine learning model. In response, the system selectively updates or replaces the model and may control device operation, including switching devices on or off. This enables adaptive, context-aware control across connected devices while maintaining stability against transient changes.
