Our novel contributions include:
- A [multilingual variant of the Conceptual-12M dataset](https://huggingface.co/datasets/flax-community/conceptual-12m-mbart-50-multilingual) containing 2.5M image-text pairs each in four languages - English, French, German and Spanish, translated using mBART-50 model.
- [Multilingual variants of the VQAv2 train and validation sets](https://huggingface.co/datasets/flax-community/multilingual-vqa) containing four times the original data in English, French, German and Spanish, translated using Marian models.
- [A fusion of CLIP Vision Transformer and BERT model](https://github.com/gchhablani/multilingual-vqa/tree/main/models/flax_clip_vision_bert) where BERT embeddings are concatenated with visual embeddings at the very beginning and passed through BERT self-attention layers. This is based on the [VisualBERT](https://arxiv.org/abs/1908.03557) model.
- A [pre-trained checkpooint](https://huggingface.co/flax-community/clip-vision-bert-cc12m-70k) on our multilingual Conceptual-12M variant with **67.85%** validation accuracy.
- A [fine-tuned checkpoint](https://huggingface.co/flax-community/clip-vision-bert-vqa-ft-6k) on our multilingual variant of the VQAv2 dataset with **49.76%** validation accuracy.
