What makes LayoutLM different from a standard BERT model for document understanding?

A.LayoutLM processes documents as pixel grids and performs masked image modeling instead of masked language modeling, treating each document as a raw image rather than an OCR-extracted token sequence
B.LayoutLM uses a vision transformer to encode the full document image before passing the resulting visual tokens to BERT for language modeling over both text and image features
C.LayoutLM replaces WordPiece tokenization with character-level byte pair encoding specifically designed to handle OCR noise, misspellings, and degraded scan quality found in scanned document inputs
D.LayoutLM incorporates 2D positional embeddings encoding the x_min, y_min, x_max, y_max bounding box coordinates of each OCR token alongside the standard token and segment embeddings
