Deep learning-based Optical Character Recognition (OCR) has become a vital tool in various industries, enabling efficient text extraction from digital and scanned documents without human intervention. This approach involves a three-step process: preprocessing to handle image quality issues, text detection using models like Mask-RCNN and YoloV5, and text recognition with RNNs, CNNs, and Attention networks. Challenges in developing such models include data collection, labeling, training infrastructure, and deployment, especially in regulated sectors like finance. Solutions such as using image augmentation, transfer learning, and automated testing can enhance model performance and efficiency. The article emphasizes learning from past experiences and iterative experimentation to optimize OCR models, highlighting the importance of adapting to technological advances and leveraging tools like Neptune for monitoring and debugging in ML workflows.
