Bagguette Boy English-French Translation Model

Model Overview

This is a bidrection English ↔ French translation model that is built on top of the BERT Encoder-Decoder model architecture. It was trained on the en-fr subset of the OPUS-100 dataset where the translations were flipped during pre-processing to double as a French to English dataset.

Model type: Encoder-Decoder (BERT-based)
Languages: English (en) ↔ French (fr)
Tasks: Machine translation, text-to-text generation
Framework: Transformers (Hugging Face)
Tokenizer: PreTrainedTokenizerFast using a custom tokenizer trained on the dataset

How to Use

The model makes use of special tokens to indicate the target language for translation:

<2fr>: Indicates that the input text should be translated to French.
<2en>: Indicates that the input text should be translated to English.

python

from transformers import AutoTokenizer, pipeline

model_path = "baguette-boy-en-fr"

tokenizer = AutoTokenizer.from_pretrained(model_path)
translator = pipeline("translation", model=model_path, tokenizer=tokenizer)

translation_output = translator("<2fr> Hello, how are you?")
print(translation_output[0]["translation_text"].replace(" ", "").replace("Ġ", " "))

translation_output = translator("<2en> Bonjour, comment ça va?")
print(translation_output[0]["translation_text"].replace(" ", "").replace("Ġ", " "))

Model Architecture

Encoder: 6-layer BERT with 8 attention heads
Decoder: 6-layer BERT with 8 attention heads, cross-attention enabled
Maximum sequence length: 128 tokens

Training Data

Dataset: OPUS-100 en-fr subset
Data preprocessing: Translations were flipped to create a bidirectional dataset
- Added special tokens <2fr> and <2en> to indicate target language
- Tokenized sequences with a custom tokenizer up to 128 tokens
- Special tokens used: <s> (BOS), </s> (EOS), [PAD], [UNK]
Data Size: Approximately 2 million sentence pairs which is 2x the original size of the en-fr subset because of the bidirectional flipping
Splits:
- Training: train
- Validation: validation

Training Details

Learning rate: 5e-5 with linear decay and warmup
Epochs: 3
Precision: fp16
Hardware: NVIDIA RTX 4070 Mobile GPU
