Converts scanned or digital images of scientific papers, technical documents, and academic PDFs into structured Markdown text using a vision-encoder-decoder architecture. The model employs a Swin Transformer vision encoder to extract spatial features from document images, then decodes them into LaTeX-compatible Markdown using a transformer decoder trained on arXiv papers. This enables preservation of mathematical equations, tables, and hierarchical document structure in machine-readable format.
Unique: Trained specifically on arXiv papers using a vision-encoder-decoder architecture that preserves mathematical equations and scientific notation in Markdown/LaTeX format, rather than generic OCR that treats equations as image regions. Uses Swin Transformer for hierarchical visual feature extraction optimized for document structure.
vs alternatives: Superior to traditional OCR (Tesseract, EasyOCR) for scientific documents because it understands equation context and outputs LaTeX-compatible Markdown; more specialized than general vision-language models (CLIP, LLaVA) which lack equation-aware training data.
Enables efficient batch processing of multiple document images through the Hugging Face Transformers library's pipeline abstraction, supporting dynamic batching and automatic device placement (CPU/GPU). The model integrates with the standard transformers.pipeline() interface, allowing developers to load the model once and process multiple images with automatic tensor batching, memory management, and optional GPU acceleration without manual CUDA code.

Extracts text from scientific document images while preserving mathematical equations in LaTeX format, using a decoder trained on arXiv papers where equations are annotated with their source LaTeX. The model learns to recognize equation regions in images and generate corresponding LaTeX code rather than attempting to OCR equations as plain text, enabling downstream tools to render or parse equations correctly.
Unique: Trained on arXiv papers with ground-truth LaTeX annotations, enabling the model to generate valid LaTeX code for equations rather than treating them as generic image regions. Decoder is specifically optimized for mathematical notation through exposure to millions of equation examples.
vs alternatives: Produces valid LaTeX output unlike generic OCR which treats equations as text; more accurate than vision-language models without equation-specific training because it learned equation-to-LaTeX mappings directly from arXiv source.
Implements a modular vision-encoder-decoder architecture where a Swin Transformer encoder extracts hierarchical visual features from document images, and a transformer decoder generates Markdown text token-by-token. The encoder processes images at multiple scales (4×, 8×, 16×, 32×) to capture both fine details and document structure, while the decoder uses cross-attention to align generated text with visual features, enabling structured output generation.
Unique: Uses Swin Transformer's hierarchical window-based attention for efficient multi-scale feature extraction, combined with a transformer decoder that uses cross-attention to align text generation with visual features. This enables structured output generation that respects document layout.
vs alternatives: More efficient than ViT-based encoders because Swin uses local attention windows; more structured than end-to-end sequence-to-sequence models because it explicitly models visual hierarchy and cross-modal alignment.
