A bilateral heterogeneous graph model for interpretable job recommendation considering both reciprocity

《工程管理前沿（英文）》 2024年 第11卷 第1期   页码 128-142 doi: 10.1007/s42524-023-0280-2

摘要： Amidst the inefficiencies of traditional job-seeking approaches in the recruitment ecosystem, the importance of automated job recommendation systems has been magnified. However, existing models optimized to maximize user clicks for general product recommendations prove inept in addressing the unique challenges of job recommendation, namely reciprocity and competition. Moreover, sparse data on online recruitment platforms can further negatively impact the performance of existing job recommendation algorithms. To counteract these limitations, we propose a bilateral heterogeneous graph-based competition iteration model. This model comprises three integral components: 1) two bilateral heterogeneous graphs for capturing multi-source information from people and jobs and alleviating data sparsity, 2) fusion strategies for synthesizing attributes and preferences to produce mutually beneficial job matches, and 3) a competition-enhancing strategy for dispersing competition realized through a two-stage optimization algorithm. Augmented by granular attention mechanisms for enhanced interpretability, the model’s efficacy, competition dispersion, and interpretability are validated through rigorous empirical evaluations on a real-world recruitment platform.

摘要： 对空分复用技术中的非理想因素进行了理论分析，并探讨了在上述非理想工程条件下空分复用的应用，给出了实测数据。对于信道条件非理想的场景，即多通道之间相关性高，条件数大，导致高层间干扰，需要通过最优化用户匹配和降维达到最优容量。对于信道测量非理想的场景，深入分析了反馈式和非反馈式的优劣，并指出即使信道不满足互易性条件，非反馈式也是优选方法。针对上述问题，进行了理论分析和外场实测。
