Dynamic heterogeneous network representation learning method based on Hawkes process

Publikováno v: Dianxin kexue, Vol 40, Pp 78-93 (2024)

Existing methods for heterogeneous network representation learning mainly focus on static networks, overlooking the significant impact of temporal attributes on node representations. However, real heterogeneous information networks are very dynamic,

Meta-path convolution based heterogeneous graph neural network algorithm

Autor: QIN Zhilong, DENG Kun, LIU Xingyan

Publikováno v: Dianxin kexue, Vol 40, Pp 89-103 (2024)

In the multilayer graph convolution calculation, each node is usually represented as a single vector, which makes the high-order graph convolution layer unable to distinguish the information of different relationships and sequences, resulting in the
