Computer-Implemented System And Method For Distributed Activity Detection
First Claim
1. A computer-implemented system for distributed activity detection, comprising:
- at least one of a mobile computing device and a sensor device to process contextual data for a user performing an activity, to extract features from the contextual data via the mobile computing device, to compare the features with a set of models stored on the mobile computing device, wherein each model represents an activity, to assign a confidence score to each model based on the comparison with the features, to transmit the features to a server when the confidence scores for each model are low; and
a server to train a new model on the server using the features and to send the new model to the mobile computing device or the sensor device.

Abstract
A computer-implemented system and method for distributed activity detection is provided. Contextual data collected for a user performing an activity is processed on a mobile computing device. The mobile computing device extracts features from the contextual data and compares the features with a set of models. Each model represents an activity. A confidence score is assigned to each model based on the comparison with the features and the mobile computing device transmits the features to a server when the confidence scores for the models are low. The server trains a new model using the features and sends the new model to the mobile computing device.
