New regularization technique improves knowledge graph embedding generalization

Researchers have conducted a comprehensive empirical study on regularization techniques for knowledge graph embedding (KGE) models, focusing on their impact on generalization. The study found that overfitting is a common issue across various KGE model families, and that appropriate regularization can significantly enhance both generalization and predictive performance. To address this, the paper proposes Sparse Peak Regularization (SPR), a novel, model-agnostic regularizer designed to selectively apply penalties to dominant embedding components, thereby improving generalization without suppressing potentially useful weak signals. Experiments across eight benchmark datasets and diverse KGE models demonstrate that SPR outperforms existing regularizers. AI

IMPACT This research offers a new method to improve the accuracy and generalization of knowledge graph embeddings, potentially enhancing downstream applications like search and recommendation systems.
