Publications

LILA-BOTI: Leveraging Isolated Letter Accumulations By Ordering Teacher Insights for Bangla Handwriting Recognition. ICPR 2022, Montréal Québec.

Abstract: Word-level handwritten OCR remains a challenge for morphologically rich languages like Bangla. This paper introduces two knowledge distillation methods improving performance on minor classes and overall word recognition rates. Evaluations showed up to 4.5% increase in recognition rate compared to base models.
