Adversarial recommendation model based on user-specific space

Abstract： Autoencoder and generative adversarial networks, as powerful models, have been applied to the field of recommendation systems to supplement the interactive information between users and items However, under this mode of training, a large amount of auxiliary information is wasted, such as userspecific information This paper combines autoencoder, generative adversarial networks, and auxiliary information to propose an adversarial recommendation model based on userspecific space (USSGAN). In order to establish the connection between auxiliary information and interactive information, the hidden space of the autoencoder is replaced by the userspecific space The pointtopoint mapping of interactive information and userspecific information limits the representation of the model Therefore, the adversarial training is added to the userspecific space to improve the performance of the modelExtensive experiments on two public movie datasets demonstrate the effectiveness and superiority of the proposed model
