摘要:

训练最先进的离线手写识别(HWR)模型需要大型标记数据集,但不幸的是,由于人工标记的高成本,这样的数据集并不适用于所有语言和领域。我们通过展示如何利用高资源语言来帮助低资源语言的训练模型来解决这个问题。我们提出了一种迁移学习方法,在这种方法中,我们调整在源语言上训练的HWR模型,使用相同书写脚本的目标语言。该方法仅需要源语言中的标记数据、目标语言中的未标记数据以及目标语言的语言模型。该语言模型用于自举的方式来完善预测的目标语言作为地面真理在训练model.Using这种方法,我们证明了提高可移植性之间的法语,英语和西班牙语使用历史和现代手写数据集。在最好的情况下,使用所提出的方法进行传输,其字符出错率几乎与全监督训练一样好。

英文摘要:

Training state-of-the-art offline handwriting recognition (HWR) models requires large labeled datasets, but unfortunately such datasets are not available in all languages and domains due to the high cost of manual labeling.We address this problem by showing how high resource languages can be leveraged to help train models for low resource languages.We propose a transfer learning methodology where we adapt HWR models trained on a source language to a target language that uses the same writing script.This methodology only requires labeled data in the source language, unlabeled data in the target language, and a language model of the target language. The language model is used in a bootstrapping fashion to refine predictions in the target language for use as ground truth in training the model.Using this approach we demonstrate improved transferability among French, English, and Spanish languages using both historical and modern handwriting datasets. In the best case, transferring with the proposed methodology results in character error rates nearly as good as full supervised training.
