“…Predicting whether a user will click on the recommended item is an essential problem in recommendation systems ( Sangaiah et al, 2023 ; Guo et al, 2022 ; Aljunid & Huchaiah, 2022 ). In CTR prediction models, commonly used algorithms include linear regression (LR), gradient boosted decision tree (GBDT), FM, FFM, DeepFM, WDL, deep Interest Network (DIN), deep interest evolution network (DIEN), and others.…”

With the exponential growth of network resources, recommendation systems have become successful at combating information overload. In intelligent recommendation systems, the prediction of click-through rates (CTR) plays a crucial role. Most CTR models employ a parallel network architecture to successfully capture explicit and implicit feature interactions. However, the existing models ignore two aspects. One limitation observed in most models is that they focus only on the interaction of paired term features, with no emphasis on modeling unary terms. The second issue is that most models input characteristics indiscriminately into parallel networks, resulting in network input oversharing. We propose a disentangled self-attention neural network based on information sharing (DSAN) for CTR prediction to simulate complex feature interactions. Firstly, an embedding layer transforms high-dimensional sparse features into low-dimensional dense matrices. Then, the disentangled multi-head self-attention learns the relationship between different features and is fed into a parallel network architecture. Finally, we set up a shared interaction layer to solve the problem of insufficient information sharing in parallel networks. Results from experiments conducted on two real-world datasets demonstrate that our proposed method surpasses existing methods in predictive accuracy.
