Abstract
A system can include multiple WiFi-enabled commercial off the shelf (COTS) Internet of Things (IoT) devices disposed within an environment and configured to be a transmitter (TX) or a received (RX) to send or receive data over a WiFi radio frequency communication link. A server can be configured to receive and parse the CSI data transmitted from the RX, store the CSI data with a corresponding human identity label collected for training, train a human identification classifier using a Convex Clustered Concurrent Shapelet Learning (CSL) method, and estimate an identification of a user based on the CSI data and the CSL method. The server can be configured to receive and parse the CSI data transmitted from the RX, transfer the CSI data into real-time CSI frames, store the real-time CSI frames in a database, store the real-time CSI frames with a corresponding gesture label collected in an original environment, and estimate and identify the gesture performed by user using a trained target encoder and source classifier.
