Abstract

In the Internet, categorical features are high-dimensional and sparse, and to obtain its low-dimensional and dense representation, the embedding mechanism plays an important role in the click-through rate prediction of the recommendation system. Prior works have proved that residual network is helpful to improve the performance of deep learning models, but there are few works to learn and optimize the embedded representation of raw features through residual thought in recommendation systems. Therefore, we designed a self-residual embedding structure to learn the distinction between the randomly initialized embedding vector and the ideal embedding vector by calculating the self-correlation score, and applied it to our proposed SRFM model. Extensive experiments on four real datasets show that the SRFM model can achieve satisfactory performance compared with the superior model. Also, the self-residual embedding mechanism can improve the prediction performance of some existing deep learning models to a certain extent.
