所有预训练 OCR 字体都有两个版本。以 _NoRej 结尾的字体名称具有正则化权重,但没有剔除类别;以 _Rej 结尾的字体名称具有正则化权重和剔除类别。
为了获得更有意义的匹配结果,在预训练 OCR 字体的教学过程中使用了正则化权重,因此指定了正则化权重。关于使用拒绝类,请参阅同名章节。
All pre-trained OCR fonts are available in two versions. Font names ending with _NoRej have regularized weight but no rejection class; font names ending with _Rej have both regularized weight and a rejection class.
The regularized weight was used when teaching-in the pre-trained OCR fonts in order to achieve more meaningful matching results, so it is specified. For Using a rejection class, see the section with the same name.
