⭐ BigTranslate Construction

🌓 Large-scale Parallel Dataset Construction

In order to enhance the language capabilities of the Chinese LLaMA model to support 102 languages, we constructed a comprehensive parallel corpus dataset consisting of 102 languages. This dataset was employed to continue training the foundational model. The compilation of this dataset drew upon multiple sources, including widely available public parallel corpus datasets and household datasets. The public datasets utilized in our study contain IWSLT, WMT, CCMT, and OPUS-100, forming the initial corpus of our dataset.

To effectively illustrate the distribution of the corpus, we present a visual representation of the language-pair distribution within the multilingual datasets. The matter pertaining to the imbalance between high-resource and low-resource language pairs continues to be a prominent concern within the current corpus.

🌔 Incremental Multilingual Pre-training

In this incremental pre-training method, we gradually expose the model to language pairs in a curriculum-like manner. Initially, the model is exposed to high-resource language pairs, allowing it to establish a solid foundation in those languages. Subsequently, we progressively introduce low-resource language pairs, enabling the model to gradually expand its knowledge and proficiency in these languages.

Specifically, we follow a three-step approach in our incremental pre-training method. Firstly, we set the sample interval size and divide language pairs into distinct intervals based on the number of instances for each language pair. Secondly, we calculate the sample mean for all language pairs in each interval. Thirdly, we dynamically measure the moment of adding the language-pair samples next interval according to the sample mean in the previous sample interval. In the following part, we detail the three steps.

🌕 Multilingual Translation Instruction Tuning

We have designed a set of 28 multilingual translation prompts that encompass various application scenarios for multilingual translation. We randomly select a prompt from the set for instruction tuning for each parallel sentence. Accordingly, the instruction tuning dataset is scrambled to ensure randomness and diversity.

During training phase, We randomly select a prompt from the following 28 multilingual translation prompts for each sentence.

📌 Model Inference

Install dependencies:

pip install -r requirements.txt

Example usage:

python -u model/inference.py \
  --model ${CHECKPOINT_PATH} \
  --tokenizer-path ${TOKENIZER_PATH} \
  --prompt-file ${PROMPT_FILE} \
  --with-instruct \
  --out-file ${LOW_OUT_FILE} \
  --seed ${SEED} \
  --beam-search \
  --num-beams ${NUM_BEAMS} \
