V-GlórIA - Customizing Large Vision and Language Models to European Portuguese

Afonso Simplício, David Semedo, Joao Magalhaes


Abstract
Generative Vision and Language models have obtained remarkable results recently, thanks to the use of robust pre-trained Visual encoders and Large Language Models (LLMs), together with efficient model adaptation training strategies, requiring minimal architecturalmodifications, while preserving LLMs’ original capabilities. With these advances focusing mainly on the English language, there is a gap in customization methodologies for other languages. In this paper, we propose a customization methodology that adapts existingstate-of-the-art vision and language architectures to European Portuguese (PT-PT). As a result of applying this methodology, we introduce V-GlórIA , the first Large Vision and Language generative model specifically customized for European Portuguese. V-GlórIA supports multimodal tasks such as image captioning, retrieval, and dialogue. To deliver V-GlórIA, we leverage state-of-the-art V&L architectures, and contribute with PT-PT machine-translated pre-training (CC3M PT-PT) and benchmark (MSCOCO PT-PT and VisDial PT-PT) datasets.Our experiments show that V-GlórIA delivers promising performance in text-image retrieval and downstream tasks in a zero-shot setting, such as image captioning and visual dialogue tasks, highlighting the effectiveness of our customization approach.
