Abstract: Click-through rate (CTR) prediction is one of the fundamental tasks in recommendation systems. Dual-stream models have been widely adopted in mainstream recommendation frameworks due to their superior flexibility, scalability, and efficiency in information interaction and fusion. To further enhance CTR prediction performance, this paper proposes the FJ hybrid network (FinalBlock-JRC hybrid network, FJHN), which integrates the factorized interaction block (FinalBlock) and the joint ranking and calibration loss optimization algorithm (JRC) based on the structure of the dual-stream model. First, a feature gating layer is introduced to enable differentiated feature inputs, thereby enhancing the representation of important features. Then, FinalBlock is combined with a multilayer perceptron (MLP) to strengthen high-order feature interaction learning. Furthermore, an enhanced interaction aggregation layer is employed to fuse the outputs of each tower, deepening the degree of feature interaction. Finally, an improved JRC mechanism is applied to compute the loss function, which effectively improves the model’s prediction accuracy and adaptability across diverse application scenarios. Experimental results on three publicly available benchmark datasets demonstrate that compared with several mainstream models including self-attention model (SAM), the FJHN model achieves noticeable performance gains in CTR prediction.
