• Abstract: Large Language Models (LLMs) demonstrate strong reasoning capabilities for many tasks, often by explicitly decomposing the task via Chain-of-Thought (CoT) reasoning. Recent work on LLM-based translation designs hand-crafted prompts to decompose translation, or trains models to incorporate intermediate steps.~\textit{Translating Step-by-step}~\citep{briakou2024translating}, for instance, introduces a multi-step prompt with decomposition and refinement of translation with LLMs, which achieved state-of-the-art results on WMT24. In this work, we scrutinise this strategy's effectiveness. Empirically, we find no clear evidence that performance gains stem from explicitly decomposing the translation process, at least for the models on test; and we show that simply prompting LLMs to ``translate again'' yields even better results than human-like step-by-step prompting. Our analysis does not rule out the role of reasoning, but instead invites future work exploring the factors for CoT's effectiveness in the context of translation.

  Machine Translation has been shown to benefit from in-context examples when they are semantically similar to the sentence to translate.<n>We propose a new LLM-based translation paradigm, compositional translation, to replace naive few-shot MT with similarity-based demonstrations.<n>Our intuition is that this approach should improve translation because these shorter phrases should be intrinsically easier to translate and easier to match with relevant examples.

  Large language models (LLMs) can achieve remarkable translation performance using only a small amount of parallel data. SFT simply instructs the model to imitate the reference translations at the token level, making it vulnerable to the noise present in the references. We propose a preference-based approach built upon the Plackett-Luce model to overcome this plateau.

  Off-target translation remains an unsolved problem, especially for low-resource languages. Recent works have either designed advanced prompting strategies to highlight the functionality of translation instructions or exploited the in-context learning ability of LLMs. In this work, we design a two-stage fine-tuning algorithm to improve the instruction-following ability (especially the translation direction) of LLMs.
