Travel state feature extraction method and device, network training method and device and electronic equipment

The invention provides a travel state feature extraction method and device, a network training method and device and electronic equipment, and relates to the technical field of data processing, in particular to the fields of big data, artificial intelligence and intelligent recommendation. According to the specific implementation scheme, various types of travel-related data of at least one target user are acquired, feature coding processing is performed on the various types of travel-related data, and coding features are obtained; performing group division on each target user based on the first target coding feature to obtain at least one user group; constructing a heterogeneous graph based on the second target coding features of the target users in each user group; performing graph representation learning based on the heterogeneous graph, and determining node features corresponding to each node; and performing feature fusion processing on each node feature to obtain a travel state feature of each target user
