Wireless terminal user portrait construction method based on WAPI communication

The method and the system relate to the technical field of wireless communication, and comprise the following steps: acquiring WAPI communication data, constructing a three-dimensional tensor to capture a WAPI communication data relationship, and retaining an original structure and a relationship of the data through tensor decomposition; a feature embedding model is constructed based on tensor construction decomposition; a comprehensive user portrait scoring model is output through user characteristic relation analysis; and correcting output features of the comprehensive user portrait scoring model according to user feedback. According to the WAPI communication-based wireless terminal user portrait construction method provided by the invention, through tensor construction and tensor decomposition extraction feature embedding, data is captured and the original structure and relation of the data are reserved, so that compressed and information-rich user representation and higher prediction accuracy of the same
