New ByT5 model tackles mixed-script OCR errors in Uzbek text

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach to correct optical character recognition (OCR) errors in mixed-script Uzbek text, a common issue due to the ongoing transition between Cyrillic and Latin alphabets. The system utilizes a byte-level ByT5 model combined with a custom noise generator trained on manually classified errors. This method significantly reduces character error rates and restores a high percentage of visually similar character errors, while introducing minimal new mistakes. AI

IMPACT Introduces a specialized technique for improving OCR accuracy in multilingual contexts, potentially applicable to other languages with similar script transition challenges.

    Post-OCR Correction of Mixed-Script Uzbek Text: Byte-Level ByT5 with an Empirical Homoglyph Noise Matrix

    arXiv:2611.13609v1 Announce Type: new Abstract: In Uzbek official and technical documents, a large share of OCR errors is caused not by poor image quality but by characters that are visually identical across the two alphabets in use. Because the script transition is still under w…
