processing data at a first electronic device and based on a first data processing model to generate an initial result, a data size of the initial result being smaller than a data size of the data, the first electronic device comprising an edge device of an edge portion of an edge-cloud network, the edge device being coupled between a user device and a cloud portion of the edge-cloud network; and

sending the initial result to a second electronic device, the initial result being adjusted at the second electronic device and based on a second data processing model to generate an adjusted result, the second electronic device comprising a cloud device of the cloud portion of the edge-cloud network;

wherein the second electronic device has more computing resources than the first electronic device, the second data processing model occupies more computing resources than the first data processing model, and an accuracy of the adjusted result is higher than that of the initial result; and

wherein the first and second electronic devices are deployed in the respective edge and cloud portions of the edge-cloud network and implement the respective first and second data processing models as respective first and second sequential stages of a separable multi-stage data processing model, the first sequential stage comprising a sensing stage of the separable multi-stage data processing model and the second sequential stage comprising a fine-adjusting stage of the separable multi-stage data processing model.
