LXMERT is a large-scale transformer model designed for learning joint representations of visual and textual data. It focuses on tasks that require reasoning over both images and language, such as Visual Question Answering (VQA) and image captioning. The model integrates a language encoder, an object relationship encoder, and a cross-modality encoder to effectively align and fuse multimodal information.
