满文OCR通过结合合成与真实历史数据得到提升

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员探索了改进濒危满语的光学字符识别（OCR）的方法，满语曾是清朝的重要语言。一项结合合成与真实历史词图像的研究表明，引入真实数据可显著提高准确性，将性能提升至超过95%的词准确率，而仅使用合成数据训练的准确率最高不超过88%。研究评估了不同的训练策略，发现联合训练和顺序训练方法均取得了相似的结果，并且紧凑型卷积循环神经网络（CRNN）在用真实图像训练时可以达到顶级性能。通过强识别器之间的误差互补投票，在无需额外训练的情况下，准确率达到了98.27%。 AI

影响 改进了濒危语言的OCR能力，可能有助于更好地访问历史档案。
