Researchers have introduced MCLMR, a novel framework designed to improve multi-behavior recommendation systems. This model-agnostic approach addresses challenges in modeling confounding effects from user habits and item distributions, effectively aggregating heterogeneous auxiliary behaviors, and aligning representations across different interaction types while mitigating bias. MCLMR utilizes a causal graph for unbiased preference estimation, an Adaptive Aggregation module for fusing behavior information, and a Bias-aware Contrastive Learning module for cross-behavior alignment. Experiments on real-world datasets show significant performance gains across various baseline models, demonstrating MCLMR's effectiveness and general applicability. AI
