quickmt-tr-en Neural Machine Translation Model

quickmt-tr-en is a reasonably fast and reasonably accurate neural machine translation model for translation from tr into en.

Model Information

• Trained using eole
• 195M parameter transformer 'big' with 8 encoder layers and 2 decoder layers
• 50k joint Sentencepiece vocabulary
• Exported for fast inference to CTranslate2 format
• Training data: https://huggingface.co/datasets/quickmt/quickmt-train.tr-en/tree/main

See the eole model configuration in this repository for further details and the eole-model for the raw eole (pytorch) model.

Usage with quickmt

You must install the Nvidia cuda toolkit first, if you want to do GPU inference.

Next, install the quickmt python library.

git clone https://github.com/quickmt/quickmt.git
pip install ./quickmt/

Finally, use the model in python:

from quickmt import Translator
from huggingface_hub import snapshot_download

# Download Model (if not downloaded already) and return path to local model
# Device is either 'auto', 'cpu' or 'cuda'
t = Translator(
    snapshot_download("quickmt/quickmt-tr-en", ignore_patterns="eole-model/*"),
    device="cpu"
)

# Translate - set beam size to 1 for faster speed (but lower quality)
sample_text = "Halifax, Nova Scotia'daki Dalhousie Üniversitesi'nde tıp profesörü ve Kanada Diyabet Derneği'nin klinik ve bilim alanı başkanı olan Dr. Ehud Ur, çalışmanın henüz başlangıç aşamasında olduğu konusunda uyarıda bulundu."

t(sample_text, beam_size=5)

'Dr. Ehud Ur, a professor of medicine at Dalhousie University in Halifax, Nova Scotia, and head of clinical and science at the Canadian Diabetes Association, warned that the study is still in its infancy.'

# Get alternative translations by sampling
# You can pass any cTranslate2 `translate_batch` arguments
t([sample_text], sampling_temperature=1.2, beam_size=1, sampling_topk=50, sampling_topp=0.9)

'Dr. Ehud Ur, a professor of medicine at Dalhousie University in Halifax, Nova Scotia, and chief clinical and science officer of the Canadian Diabetes Society, warned that the study is still at its preliminary stage.'

The model is in ctranslate2 format, and the tokenizers are sentencepiece, so you can use ctranslate2 directly instead of through quickmt. It is also possible to get this model to work with e.g. LibreTranslate which also uses ctranslate2 and sentencepiece.

Metrics

bleu and chrf2 are calculated with sacrebleu on the Flores200 devtest test set ("tur_Latn"->"eng_Latn"). comet22 with the comet library and the default model. "Time (s)" is the time in seconds to translate the flores-devtest dataset (1012 sentences) on an RTX 4070s GPU with batch size 32 (faster speed is possible using a larger batch size).
