Unicoder-VL is a universal encoder for vision and language that learns joint representations through cross-modal pre-training. Inspired by cross-lingual pre-trained models like XLM and Unicoder, Unicoder-VL uses a multi-layer Transformer to process both visual and linguistic data. It employs three pre-training tasks: Masked Language Modeling (MLM), Masked Object Classification (MOC), and Visual-Linguistic Matching (VLM). These tasks help learn context-aware representations and model relationships between visual and linguistic content. After pre-training on large-scale image-caption pairs, Unicoder-VL is fine-tuned for image-text retrieval and visual commonsense reasoning, achieving state-of-the-art results. The model demonstrates strong cross-modal learning capabilities and generalization. It outperforms existing methods on tasks like image-text retrieval and visual commonsense reasoning, showing the effectiveness of cross-modal pre-training. The model is versatile and can be applied to various cross-modal tasks beyond image-text retrieval. Unicoder-VL is pre-trained using image-caption pairs, which are easy to collect and have good quality. The model's performance is evaluated on datasets like MSCOCO and Flickr30K, and it achieves high accuracy in both image-text retrieval and visual commonsense reasoning. The model's architecture includes a multi-layer Transformer for joint visual and linguistic representation learning. It is trained on large-scale image-caption pairs and fine-tuned for downstream tasks. The model's performance is compared with other state-of-the-art methods, showing its effectiveness in cross-modal tasks. The model's results indicate that cross-modal pre-training significantly improves performance on visual commonsense reasoning tasks. The model is also tested in a zero-shot setting, demonstrating its ability to generalize without task-specific fine-tuning. The model's architecture and training process are detailed, showing how it learns joint representations and performs on various tasks. The model's results on image-text retrieval and visual commonsense reasoning tasks indicate its effectiveness and versatility. The model's performance is compared with other methods, showing its superiority in cross-modal tasks.
