Abstract

The embodiment of the invention provides a classification model training method and device, electronic equipment and a storage medium, which are applied to the technical field of information, and the method comprises the steps of generating a sample heterogeneous graph according to a sample heterogeneous graph, extracting a semantic graph, generating a relation sub-graph, obtaining a classification result of a to-be-classified target according to the relation sub-graph, calculating the current loss, and adjusting the parameters of the to-be-trained heterogeneous graph structure learning network and the to-be-trained graph neural network at the same time according to the current loss, so that the model training efficiency can be improved.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a classification model training method, device, electronic equipment and storage medium. Background technique [0002] A heterogeneous graph refers to a graph containing many different types of nodes and relationships. In reality, heterogeneous graphs can often better reflect the relationship between objects to be classified. For example, when classifying movies and actors, the same actor may appear in multiple movies, and the same movie may include multiple actors. [0003] However, when training the classification model of the heterogeneous graph of the object to be classified, the heterogeneous graph is directly identified and the object to be classified is classified, because the relationship between the nodes in the heterogeneous graph is often complicated, and the observed The obtained heterogeneous graph structure often cannot reflect this complex relations...
