This research addresses a critical bottleneck in document AI by replacing order-dependent autoregressive decoding with non-causal attention for table recognition tasks. By enabling parallel inference while maintaining global consistency, the proposed structural refinement module significantly accelerates processing speeds without sacrificing accuracy on complex multi-task frameworks. For practitioners deploying large-scale data extraction systems, this approach offers a tangible path to reducing latency in structured document parsing pipelines.
Revisiting Structural Dependency in Autoregressive Multi-Task Table Recognition via Order-Independent Cell-Level Representations
arXiv:2606.17874v1 Announce Type: cross Abstract: Multi-task table recognition jointly addresses table structure prediction, cell localization, and cell content recognition within a unified framework. Existing approaches often rely on autoregressive decoders to generate table structures and reuse their hidden states for cell localization and content recognition. This autoregressive generation process can make cell representations order-dependent, degrading global consistency across cells. This paper proposes a structural refinement module that produces order-independent cell features through non-causal attention. This design enables parallel inference of cell contents while conditioning each cell on global context encoded in the refined features. Experiments on two large datasets demonstrate consistent gains in cell localization and end-to-end recognition, while reducing overall inference time by around threefold.
