Knowledgebra: An Algebraic Learning Framework for Knowledge Graph

no code implementations15 Apr 2022 Tong Yang, Yifei Wang, Long Sha, Jan Engelbrecht, Pengyu Hong

As far as we know, by applying abstract algebra in statistical learning, this work develops the first formal language for general knowledge graphs, and also sheds light on the problem of neural-symbolic integration from an algebraic perspective.

Variance Regularization for Accelerating Stochastic Optimization

no code implementations13 Aug 2020 Tong Yang, Long Sha, Pengyu Hong

While nowadays most gradient-based optimization methods focus on exploring the high-dimensional geometric features, the random error accumulated in a stochastic version of any algorithm implementation has not been stressed yet.

NagE: Non-Abelian Group Embedding for Knowledge Graphs

no code implementations22 May 2020 Tong Yang, Long Sha, Pengyu Hong

We demonstrated the existence of a group algebraic structure hidden in relational knowledge embedding problems, which suggests that a group-based embedding framework is essential for designing embedding models.
