Abstract: The invention provides a distributed neural network communication system for optimizing video analytics inference on an edge computing device. The system includes an edge system and a cloud system communicatively coupled to each other, the edge system being configured to receive an input data stream from an input device and to conduct partial or preliminary feature extraction at the edge system, and the cloud system being configured to communicate with the edge system to receive an extracted feature vector from the edge system and to conduct further feature extraction at the cloud system to yield a final feature vector, thereby enhancing accuracy of a neural network of the distributed neural network communication system. A distributed neural network communication method and a computer program product for distributed neural network communication are also provided.
