The application discloses a kind of federated meta-learning image
classification methods based on sparse neural network, communication efficiency is high,
algorithm performance is good.The method of the present application mainly includes the following steps: (10) set up fully connected neural network node and
correlation coefficient, establish source node set and target node set;(20) the full connection neural network is sparsified, and the weight parameters of sparse neural network are initialized;(30) training internal update is carried out on the
training set data of each source node;External update is carried out on the
test set data of each source node;(40) remove the minimum positive number and the maximum negative number of each layer of weight matrix after external update of each source node, whether iteration number t is the integer multiple of the set local iteration number is judged to make corresponding
processing;(50) gradient update training is carried out on the
training set data in each target node based on the parameters obtained by training source node set, and image classification task is carried out using the fine-tuned model of target node.
