Title:
METEOROLOGICAL EVENT PREDICTION METHOD AND APPARATUS, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/203980
Kind Code:
A1
Abstract:
A meteorological event prediction method. The method comprises: a first terminal calculating, according to each sample in a first sample set, a first-order gradient set and a second-order gradient set of a loss function of a model to be trained; receiving an aggregated first-order gradient set and an aggregated second-order gradient set, which are sent by a second terminal and are obtained by performing calculation according to a second sample set, wherein the second sample set is a sample set which is determined from a sample set of the second terminal and is similar to the first sample set; and then training the model according to gradient values of samples and aggregated gradient values of similar samples, and predicting a meteorological situation by means of the trained model. By means of sending aggregated gradient values of similar samples to a first terminal for model training, the problem of data leakage is avoided, and similar samples of other terminals are also used during a model training process, such that a trained model is more accurate, and the terminals can perform synchronous and parallel training, thereby improving the calculation efficiency of a model, and rationally using data and resources.
