The invention provides a multi-source fusion heterogeneous
data extraction method and
system and a storage medium, and the method comprises the steps: constructing a dynamic
hypergraph neural network and a dynamic
hypergraph structure, carrying out the
feature aggregation, and obtaining a space-time enhancement feature representation; performing
causal reasoning and meta-learning optimization to generate robust feature representation; and by executing
data reconstruction and fusion, outputting a heterogeneous
data extraction result after multi-source fusion. According to the method, a dynamic
hypergraph neural network, a sliding window and an attention mechanism are combined,
data entity spatio-temporal evolution is modeled in real time, and the problem of correlation
lag of a traditional static hypergraph is solved; then, a causal element learning confrontation module integrates
causal reasoning, element learning and confrontation training to improve model robustness; finally,
data reconstruction, meta-learning and adversarial loss are subjected to weighted fusion through a joint optimization strategy, the feature expression ability is improved, and the generalization performance of the model in a
small sample scene is ensured.
