What is trocr-base-handwritten-ru?
TrOCR-base-handwritten-ru is a specialized optical character recognition (OCR) model designed specifically for Russian handwritten text. It's a fine-tuned version of Microsoft's TrOCR model, optimized for Cyrillic script recognition. The model combines a vision transformer encoder initialized from BEiT with a text transformer decoder based on RoBERTa, creating a powerful solution for converting handwritten Russian text images into machine-readable format.
Implementation Details
The model processes images by dividing them into 16x16 pixel patches and employs a transformer-based architecture for both encoding and decoding. It was trained on the Cyrillic Handwriting Dataset for 5 epochs, achieving a training loss of 0.026100 and validation loss of 0.120961.
