[0029] The present invention will be further described in detail with reference to the accompanying drawings. The present invention proposes an algorithm for link prediction using a deep confidence network classification model for undirected networks. The specific implementation methods include:
[0030] Training data set acquisition module, according to the characteristics of the deep belief network training process, this module needs to collect training edge sets, verification edge sets and test edge sets.
[0031] The network node feature representation module uses the deepwalk algorithm to obtain the feature vector representation of each network node on the network data processed by the collected data set;
[0032] Generate edge feature representation module, each edge can be represented by a node pair, we use the method of directly splicing the respective feature vectors of two node pairs to generate the feature vector representation of the corresponding edge;
[0033] Construct ...
