New Geometry-Aware Loss Boosts Table Structure Recognition Accuracy

Researchers have developed a new loss function called Geometry-Aware Pointer (GAP) Loss to improve table structure recognition (TSR) in computer vision. This novel approach addresses a common failure mode where errors occur between spatially adjacent cells, which standard cross-entropy loss does not adequately penalize. By reweighting the loss based on spatial proximity, GAP Loss directs stronger gradients towards these difficult neighboring cells. Applied to existing pointer network architectures with no added inference cost, GAP Loss has demonstrated significant improvements on benchmark datasets like PubTabNet and SynthTabNet, establishing new state-of-the-art performance by reducing adjacent-cell errors.
