基于DNN与注意力机制的推荐算法模型OACSTPCD

In order to solve the defect of factorization machine in extracting high-order combination features and learn more use-ful feature information better,this paper attempts to use factorization machine to extract cross-feature and learn key feature infor-mation from low and high-order combination features by combining attention network,deep neural network,multi-head self-attention mechanism and other methods.Finally,the weighted fusion results were obtained according to the importance of the combination features of different orders,and the click-through rate of advertisements was estimated.The experiment was mainly carried out based on the advertising data set Criteo,and the analogy experiment was carried out with MovieLens data set to verify the effectiveness of the proposed algorithm model.The experimental results showed that compared with the benchmark model,in the two data sets,the AUC index increased by 2.32 percntage points and 0.4 percntage points.
