## 1. 简介
PP-OCRv3是百度开源的超轻量级场景文本检测识别模型库,其中超轻量的场景中文识别模型SVTR_LCNet使用了SVTR算法结构。为了保证速度,SVTR_LCNet将SVTR模型的Local Blocks替换为LCNet,使用两层Global Blocks。在中文场景中,PP-OCRv3识别主要使用如下优化策略:

**(6)UIM:无标注数据挖掘方案**
UIM(Unlabeled Images Mining)是一种非常简单的无标注数据挖掘方案。核心思想是利用高精度的文本识别大模型对无标注数据进行预测,获取伪标签,并且选择预测置信度高的样本作为训练数据,用于训练小模型。使用该策略,识别模型的准确率进一步提升到79.4%(+1%)。

**(6)UIM:Unlabeled Images Mining**
UIM (Unlabeled Images Mining) is a very simple unlabeled data mining strategy. The main idea is to use a high-precision text recognition model to predict unlabeled images to obtain pseudo-labels, and select samples with high prediction confidence as training data for training lightweight models. Using this strategy, the accuracy of the recognition model is further improved to 79.4% (+1%).
