We investigate transfer learning based on pre-trained neural machine translation models to translate between (low-resource) similar languages. This work is part of our contribution to the WMT 2021 Similar Languages Translation Shared Task where we submitted models for different language pairs, including French-Bambara, Spanish-Catalan, and Spanish-Portuguese in both directions. Our models for Catalan-Spanish ($82.79$ BLEU) and Portuguese-Spanish ($87.11$ BLEU) rank top 1 in the official shared task evaluation, and we are the only team to submit models for the French-Bambara pairs.

翻译：这项工作是我们对WMT 2021年类似语言翻译共同任务的贡献的一部分,我们在该任务中提交了两种不同语言模式的模型,包括法语-班巴拉语、西班牙语-卡塔兰语和西班牙语-葡萄牙语。 我们的加泰罗尼亚-西班牙语模式(82 79美元比莱欧)和葡萄牙语-西班牙语模式(87.11美元比莱欧)在正式分担任务评价中排名第一,我们是唯一为法语-班巴拉语组合提交模型的团队。
