Abstract: A profit-aware Offloading Framework towards Prediction-assisted MEC Network Slicing is provided. Towards MEC network slicing, formulate the optimization problem of maximizing long-term ESP profits and decouple it into the sub-problems of Edge network Slicing (EnS) and Computation offloading Access (CoA). For the slicing sub-problem, use a gated recurrent neural network (GRNN) to accurately predict user requests in different regions, and then use the optimal partitioning of network slices with the predicted requests and expected demands; For the offloading sub-problem, incorporating results from slice partitioning, use an improved deep reinforcement learning with twin ritic-networks and delay mechanism, solving the Q-value overestimation and high variance for approximating the optimal offloading and resource allocation.

Abstract: The present disclosure provides a method and system for efficiently and securely managing human motion data. In one aspect, a human-motion-data-managing system first receives a sequence of video images including a first person. Next, for each image in the sequence of video images, the human-motion-data-managing system detects the first person in the video image; and subsequently extracts a skeleton figure of the detected first person from the image, wherein the skeleton figure is composed of a set of human keypoints. Next, human-motion-data-managing system combines a sequence of extracted skeleton figures of the detected first person from the sequence of video images to form a skeleton sequence of the detected first person which depicts a continuous motion of the first person. The human-motion-data-managing system subsequently transmits the skeleton sequence to a server in place of the actual images of the first person to preserve the privacy of the first person.
