Graphlets as Building Blocks for Structural Vocabulary in Knowledge Graph Foundation Models
Kossi Amouzouvi, Robert Wardenga, Jens Lehmann +1
Foundation models excel at language, where sentences become tokens, and vision, where images become pixels, because both reduce to discrete symbols on a shared, fixed grid. Knowled…
Aligning Knowledge Graphs and Language Models for Factual Accuracy
Nur A Zarin Nishat, Andrea Coletta, Luigi Bellomarini +3
Large language models like GPT-4, Gemini, and Claude have transformed natural language processing (NLP) tasks such as question answering, dialogue generation, summarization, and so…
SMART: Relation-Aware Learning of Geometric Representations for Knowledge Graphs
Kossi Amouzouvi, Bowen Song, Andrea Coletta +3
Knowledge graph representation learning approaches provide a mapping between symbolic knowledge in the form of triples in a knowledge graph (KG) and their feature vectors. Knowledg…
Modelling the impact of vaccination on the COVID-19 pandemic in African countries
Dephney Mathebula, Abigail Amankwah, Kossi Amouzouvi +13
The rapid development of vaccines to combat the spread of COVID-19 disease caused by the SARS-CoV-2 virus is a great scientific achievement. Before the development of the COVID-19…
Hilbert space representation of maximal length and minimal momentum uncertainties
Kossi Amouzouvi, Benjamin A. Appiah, Latévi M. Lawson +1
Perivolaropoulos has recently proposed a position-deformed Heisenberg algebra which includes a maximal length [Phys.Rev.95, 103523 (2017)]. He has shown that this length scale natu…
A model of COVID-19 pandemic evolution in African countries
Kossi Amouzouvi, Kétévi A. Assamagan, Somiéalo Azote +14
We studied the COVID-19 pandemic evolution in selected African countries. For each country considered, we modeled simultaneously the data of the active, recovered and death cases.…
Exact Kohn-Sham Density Functional Theory on a Lattice
Kossi Amouzouvi, Daniel Joubert
We formulate a set of equations that facilitate an exact numerical solution of the Kohn-Sham potential for a finite Hubbard chain with nearest neighbour hopping and arbitrary site…
