Researchers investigated the Mutual Reinforcement Effect (MRE) in multimodal document understanding, specifically examining if combining fine-grained span-level tasks with coarse-grained document-level tasks improves performance. Their study, using three corpora including receipts and business forms, found that standard joint training did not yield significant improvements and often resulted in trade-offs between task granularities. However, a novel conditioned training approach, which incorporates the output of one task into the prompt of the other during training, showed reinforcement on two of the three datasets, particularly in avoiding performance collapse on complex document sets.
