no code implementations • Findings (NAACL) 2022 • Christos Papadopoulos, Yannis Panagakis, Manolis Koubarakis, Mihalis Nicolaou

We test our proposed method on finetuning multiple natural language understanding tasks by employing BERT-Large as an instantiation of the Transformer and the GLUE as the evaluation benchmark.

Transformers in the Service of Description Logic-based Contexts

1 code implementation • 15 Nov 2023 • Angelos Poulis, Eleni Tsalapati, Manolis Koubarakis

In this way, we systematically investigate the reasoning ability of a supervised fine-tuned DeBERTa-based model and of two large language models (GPT-3. 5, GPT-4) with few-shot prompting.
