The TasTe framework, which is short for Teaching Large Language Models to Translate through Self-Reflection, is designed as a two-stage inference process to enhance the translation quality of MT-LLMs. It consists of the following two stages:

• Stage 1: Generate preliminary translations (i.e. drafts) and conduct self-assessment of the translation quality at the same time.
• Stage 2: Refine the preliminary translations according to the predicted quality levels to obtain final outputs.

To ensure the sufficient capability for the entire self-reflective translation process, the LLMs are fine-tuned on a multi-task training set. The dataset consists of three parts:

• Basic Translation: Common parallel corpus to provide the LLMs with correct multilingual knowledge.
• Quality Prediction: Sources and translation candidates with their evaluated COMET scores to equip the LLMs with knowldge about translation quality and capabilities to make translation assessments.
• Draft Refinement: Preliminary translations with their COMET scores and enhanced translations to teach the LLMs to refine drafts according to their quality scores.

cd ReflectionLLMMT
pip install -r requirments.txt

(1) FixEmb: Tuning with Embedding Layers Fixed

• train/train_fixemb.sh

(2) Full: Tuning with Full Parameters

• train/train_full.sh

Make sure to fill in the following parameters before running:

work_dir=/path/to/ReflectionLLMMT      # path to the ReflectionLLMMT root directory
model_name=name_of_your_model          # name your model, e.g. bloom_fixemb
settings=tc                            # training settings, choices=[tc, qe, mt]
premodel=/path/to/original/checkpoint  # path to the pretrained model checkpoint directory
GPU_NUM=8                              # number of available GPUs
GPU=0,1,2,3,4,5,6,7                    # GPU ids

There are three choices of training settings, corresponsing to three different training sets:

1. tc - Fine-tune with data in data/train_tc.json to get a TasTe model in Text Classification style.
2. qe - Fine-tune with data in data/train_qe.json to get a TasTe model in Quality Estimation style.
3. mt - Fine-tune with data in data/train_mt.json to get a MT-baseline model.

• infer/test.sh

Make sure to fill in the following parameters before running:

work_dir=/path/to/ReflectionLLMMT  # path to the ReflectionLLMMT root directory
lang=zh-en                         # language pair to be tested in, choices=['zh-en', 'en-zh', 'de-en', 'en-de']
test_model=name_of_model           # name of the fine-tuned model you gave
settings=tc                        # model settings, choices=[tc, qe, mt]
GPU_NUM=8                          # number of available GPUs

There are also three choices of testing settings, corresponsing to three different training settings:

1. tc - Test a TasTe model in Text Classification style.
2. qe - Test a TasTe model in Quality Estimation style.
3. mt - Test a MT-baseline model.
