摘要:

在这项工作中,我们的目标是利用先验符号知识来提高深度模型的性能。我们提出了一个图嵌入网络,通过一个增广的图卷积网络(GCN)将命题公式(和赋值)投影到流形上。为了生成语义上忠实的嵌入,我们开发了识别节点异质性的技术,以及将结构约束纳入嵌入的语义正则化。实验表明,我们的方法提高了模型的性能训练执行蕴涵检查和视觉关系预测。有趣的是,我们观察到之间的关系的易处理性的命题理论表示和嵌入的容易性。未来对这种联系的探索可能会阐明知识编译和向量表示学习之间的关系。

英文摘要:

In this work, we aim to leverage prior symbolic knowledge to improve the performance of deep models. We propose a graph embedding network that projects propositional formulae (and assignments) onto a manifold via an augmented Graph Convolutional Network (GCN). To generate semantically-faithful embeddings, we develop techniques to recognize node heterogeneity, and semantic regularization that incorporate structural constraints into the embedding. Experiments show that our approach improves the performance of models trained to perform entailment checking and visual relation prediction. Interestingly, we observe a connection between the tractability of the propositional theory representation and the ease of embedding. Future exploration of this connection may elucidate the relationship between knowledge compilation and vector representation learning.
