Abstract | Aiming at the problem of negative migration in multi-task recommendation, the multi-task recommen-dation model of dual perception gated interaction (DPGI-MTRM) is proposed. Firstly, in the multi-task sharing network and the proprietary network, the dual-sensing feature extraction module (called the dual-sensing expert layer) is innovatively designed. Its function is to obtain the element-level and vector-level dual-sensing feature representation for the input features. Secondly, a task interaction layer is proposed on the basis of the gated network, which interactively calculates the features output by the gated network to extract high-level semantic relevance between tasks, and at the same time uses the residual method plus the original input gated feature vector to reduce possible noise interference caused by task interaction. Finally, by stacking a dual perception expert layer and a gated interaction layer, and then connecting the neural network output layer of a specific task, a multi-task recommendation model of dual perception gated interaction is obtained. In addition, the multi-objective optimization method of gradient normalization is used during model training, so that the model can better converge. Experiments are conducted on the Census-income, Synthetic Data and Ali-CCP datasets, and the AUC (area under curve) and MSE (mean square error) indicators are used for evaluation. Experimental results show that the proposed model performs better than other benchmark models and achieves more advanced performance. |
