Hebrew-English Translation Model

A fine-tuned MarianMT model for translating between Hebrew and English, specifically trained on biblical text from the New World Translation of the Holy Scriptures.

Model Description

• Model type: MarianMT (Seq2Seq)
• Language: Hebrew ↔ English
• Base model: Helsinki-NLP/opus-mt-mul-en
• Training data: New World Translation of the Holy Scriptures (Modern Hebrew translation)
• BLEU Score: 46.69 (test set)
• Character Accuracy: 26.57%

Dataset Information

The model was trained on the New World Translation of the Holy Scriptures dataset, which contains:

• Source: Modern Hebrew translation (not the original Biblical Hebrew)
• Target: English translation
• Dataset size: 30,693 training examples, 3,837 validation examples, 3,837 test examples
• Text type: Biblical scripture with religious terminology

Training Details

• Training epochs: 5.34 (early stopping)
• Learning rate: 2e-5
• Batch size: 8
• Mixed precision: FP16
• Early stopping: Enabled with patience=3
• Training time: ~3.5 hours
• Hardware: GPU training

Usage

Using the Model

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

# Load model and tokenizer
model_name =  "johnlockejrr/marianmt-he2en-nwt"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSeq2SeqLM.from_pretrained(model_name)

# Hebrew to English translation
hebrew_text = "שלום עולם"
inputs = tokenizer(hebrew_text, return_tensors="pt", padding=True)
outputs = model.generate(**inputs, max_length=128, num_beams=4)
english_translation = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(english_translation)

Using the Pipeline

from transformers import pipeline

translator = pipeline("translation", model="johnlockejrr/marianmt-he2en-nwt")

# Hebrew to English
hebrew_text = "בראשית ברא אלהים את השמים ואת הארץ"
result = translator(hebrew_text)
print(result[0]['translation_text'])

Interactive Translation

python inference.py --model_path ./hebrew_english_model --text "שלום עולם" --direction he2en

Model Performance

Evaluation Metrics

Translation Examples

Hebrew	English Translation
שלום עולם	Hello world
בראשית ברא אלהים	In the beginning God created
אהבה	Love

Limitations

1. Domain Specificity: This model is specifically trained on biblical text and may perform best on religious/scriptural content
2. Modern Hebrew: The Hebrew text is Modern Hebrew translation, not original Biblical Hebrew
3. Context Sensitivity: Translation quality may vary depending on the context and complexity of the text
4. Cultural Nuances: Some cultural and religious nuances may not be perfectly captured

    early_stopping_patience=3
)

Dataset Preparation

The dataset was prepared from the New World Translation corpus with the following preprocessing:

• Text cleaning and normalization
• Length filtering (5-1000 characters)
• Length ratio filtering (0.3-3.0)
• Train/validation/test split (80/10/10)
