Researchers have developed JETRTQA, a novel multimodal learning framework designed to improve textbook question answering by enhancing document retrieval. This model uses a retriever-generator architecture with a multimodal large language model to generate answers. JETRTQA refines semantic representations through joint training that combines pairwise ranking and implicit supervision from answers, leading to better discrimination between relevant and irrelevant documents. The approach significantly outperforms the previous state of the art on the CK12-QA dataset, achieving notable accuracy gains. AI
