Abstract: The combination of low-order and high-order features in the recommendation system is crucial to the predicted click-through rate. This paper designs an Attention Deep Cross IO-awre Factorization Machine (ADCIOFM) model. The traditional recommendation model extracts low-order and high-order features through the attention factor decomposer and deep cross-network respectively. However, the hidden field information is easily ignored when the attention factor decomposer extracts low-order combined features, and the diversity of user interests in deep cross-network mining is weak. Therefore, this paper enhances the representation ability of attention mechanism to estimate the low-order combined feature weight by incorporating the perceptual auxiliary matrix. The feature depth of different subspaces is extracted by integrating a multi-head attention mechanism to solve the problem of user interest diversity in deep cross-network mining. Finally, the low-order and high-order combined features are effectively fused for a recommendation. Through experimental comparison on Criteo and Movielens-100K data sets, the AUC index is used for evaluation, which is 0.0087 and 0.0159 higher than the benchmark model.
