• Abstract: Neural approaches have achieved state-of-the-art accuracy on machine translation but suffer from the high cost of collecting large scale parallel data. Thus, a lot of research has been conducted for neural machine translation (NMT) with very limited parallel data, i.e., the low-resource setting. In this paper, we provide a survey for low-resource NMT and classify related works into three categories according to the auxiliary data they used: (1) exploiting monolingual data of source and/or target languages, (2) exploiting data from auxiliary languages, and (3) exploiting multi-modal data. We hope that our survey can help researchers to better understand this field and inspire them to design better algorithms, and help industry practitioners to choose appropriate algorithms for their applications.

  We compare three dataset creation strategies: (1) LLM-assisted dataset generation, (2) machine translation, and (3) human-written data by native speakers, to build a culturally nuanced story comprehension dataset. Our findings indicate that LLM-assisted data creation outperforms machine translation.

  In-context machine translation (MT) with large language models (LLMs) is a promising approach for low-resource MT. This study systematically investigates how each resource and its quality affects the translation performance, with the Manchu language. Our results indicate that high-quality dictionaries and good parallel examples are very helpful, while grammars hardly help.

  Document-level neural machine translation (DocNMT) aims to generate translations that are both coherent and cohesive. Due to its longer input length and limited availability of training data, DocNMT often faces the challenge of data sparsity. We propose a novel Importance-Aware Data Augmentation (IADA) algorithm for DocNMT that augments the training data based on token importance information estimated by the norm of hidden states and training gradients.

  In machine translation, majority of the language pairs around the world are considered low resource because they have little parallel data available. We study and apply three simple data augmentation techniques popularly used in text classification tasks. We see that there is potential to use these methods in neural machine translation when more extensive experiments are done with diverse datasets.
