Inverse Transfer Data Augmentation: A Response to the Stylistic Transfer Challenge

Technological advances in natural language processing (NLP) has produced significant changes in several areas, especially in textual analysis and the transfer of writing styles. One interesting development is the research by Zhonghui Shao et al. in an article titled “Authorship Style Transfer with Inverse Transfer Data Augmentation”, published in the journal AI Open in August 2024 (Volume 5, pp. 94-103).

This article introduces a new method called Increase indirect transfer data (ITDA), which allows large-scale language models (LLMs) to perform writing style transitions more efficiently than conventional methods.

In recent years, NLP has been widely used to transfer textual styles such as expression or formality. However, individual writing style or authorial style is difficult to translate because it does not have clear attributes, such as positive-negative mood. According to this article, the ITDA method successfully demonstrated up to a 40% increase in efficiency in writing style transfer, especially compared to the traditional approach using GPT-3.5.

The advantage of ITDA lies in its reverse style transfer method, which uses neutral text to train the model. This overcomes what LLMs have in dealing with styles that rarely appear in their initial training.

Experiments conducted by Shao et al. by using four different writing style data sets, both in English and Chinese, it proved that this method is not only more accurate, but also more computationally efficient. Throughout this article, Shao et al. he made a significant contribution to the development of NLP, especially in the movement of more complex and less defined styles of writing.

The article by Shao et al. not only introduces the ITDA method, but also offers strong evidence of its effectiveness through comprehensive tests. One of the most interesting aspects of this research is how ITDA addresses the shortcomings that often arise in conventional force transfer methods, particularly in handling authority style which is difficult to explain. Shao et al. show that traditional style transfer methods such as gin sweep or hidden representation tend to fail to retain the original content of the text and face challenges in complex writing styles.

According to the results of tests carried out, ITDA produces significant improvements compared to conventional methods. For example, in an experiment using a style data set Shakespearethe ITDA method was able to achieve a BLEU score of 0.78 and a BERTScore of 0.92.

This figure is higher than the GPT-3.5 forward method which achieved only BLEU 0.65 and BERTScore 0.88. In addition, the stylistic shift (SC) score for ITDA is 0.73, which is a significant improvement from the 0.47 score produced by GPT-3.5. This data shows that ITDA is not only excellent in terms of style transfer, but also in maintaining the integrity of the original content, which is a big problem in traditional methods.

The benefits of ITDA can also be seen in its ability to overcome data limitations. In tests on the database Trump and LyricsITDA can produce text with a more detailed style although the amount of training data available is limited. Using data augmentation techniques, ITDA generated 50,000 additional pieces of data for writing styles Shakespeare and Lin Daiyutwo classic writing styles that are very difficult for language models to reproduce.
