What is recorded here?
Added text-image alignment and matching objectives with spatial-aware attention to jointly learn text, layout and image interactions for document understanding.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
December 2020 preprint precedes 2021 conference. Extends LayoutLM with specific cross-modal objectives/attention rather than inventing multimodal pretraining; benchmark gains are not production reliability certification.
