我们展示了两种最先进的链接预测/知识图完成模型的等价性:Nickel等人的全息嵌入和Trouillon等人的“。的复杂嵌入。我们首先考虑全息嵌入的频谱版本,利用傅里叶变换中的频域进行有效的计算。对所得模型的分析表明,它可以被视为复杂嵌入的一个实例,在训练时对初始向量施加了一定的约束。相反,任何一组复杂的嵌入都可以转换为一组等价的全息嵌入。
We show the equivalence of two state-of-the-art models for link prediction/knowledge graph completion: Nickel et al’s holographic embeddings and Trouillon et al.’s complex embeddings. We first consider a spectral version of the holographic embeddings, exploiting the frequency domain in the Fourier transform for efficient computation. The analysis of the resulting model reveals that it can be viewed as an instance of the complex embeddings with a certain constraint imposed on the initial vectors upon training. Conversely, any set of complex embeddings can be converted to a set of equivalent holographic embeddings.
