TWIG: Towards pre-hoc Hyperparameter Optimisation and Cross-Graph Generalisation via Simulated KGE Models

no code implementations8 Feb 2024 Jeffrey Sardina, John D. Kelleher, Declan O'Sullivan

Our experiments on the UMLS dataset show that a single TWIG neural network can predict the results of state-of-the-art ComplEx-N3 KGE model nearly exactly on across all hyperparameter configurations.

Link Prediction

A semantic web approach to uplift decentralized household energy data

no code implementations18 Aug 2022 Jiantao Wu, Fabrizio Orlandi, Tarek Alskaif, Declan O'Sullivan, Soumyabrata Dev

In a decentralized household energy system comprised of various devices such as home appliances, electric vehicles, and solar panels, end-users are able to dig deeper into the system's details and further achieve energy sustainability if they are presented with data on the electric energy consumption and production at the granularity of the device.

Poisoning Knowledge Graph Embeddings via Relation Inference Patterns

1 code implementation ACL 2021 Peru Bhardwaj, John Kelleher, Luca Costabello, Declan O'Sullivan

We study the problem of generating data poisoning attacks against Knowledge Graph Embedding (KGE) models for the task of link prediction in knowledge graphs.
