Convolutional complex knowledge graph embeddings

C Demir, ACN Ngomo - The Semantic Web: 18th International Conference …, 2021 - Springer
We investigate the problem of learning continuous vector representations of knowledge
graphs for predicting missing links. Recent results suggest that using a Hermitian inner …

Convolutional hypercomplex embeddings for link prediction

C Demir, D Moussallem, S Heindorf… - Asian Conference on …, 2021 - proceedings.mlr.press
Abstract Knowledge graph embedding research has mainly focused on the two smallest

A shallow neural model for relation prediction

C Demir, D Moussallem… - 2021 IEEE 15th …, 2021 - ieeexplore.ieee.org
Knowledge graph completion refers to predicting missing triples. Most approaches achieve
this goal by predicting entities, given an entity and a relation. We predict missing triples via …

MLCheck–property-driven testing of machine learning classifiers
