MarianMT Indonesian-English Translation (Fine-Tuned)

This model is a fine-tuned version of Helsinki-NLP/opus-mt-id-en specialized for translating Indonesian to English, particularly within contexts found in TED Talks.

🎯 Model Highlights

• Specialized Context: Fine-tuned on the TED Talks parallel corpus for better performance on formal and presentation-style language.
• Optimized Training: Utilizes modern training techniques like layer freezing and a cosine annealing scheduler for stable and effective fine-tuning.
• Production Ready: Can be easily integrated into applications using the transformers library.

🚀 Model Details

• Base Model: Helsinki-NLP/opus-mt-id-en
• Fine-tuned Dataset: Cleaned and aligned TED Talks parallel corpus (Indonesian-English).
• Training Date: 2025-06-16
• Languages: Indonesian (id) → English (en)

⚙️ Training Configuration

Hyperparameters

• Learning Rate: 5e-6
• Weight Decay: 0.001
• Gradient Clipping: 0.5
• Max Sequence Length: 96-128 tokens
• Scheduler: Cosine Annealing with Warmup

Architecture Optimizations

• Layer Freezing: Early encoder layers were frozen to preserve foundational language knowledge from the base model.
• Memory Optimization: Utilized gradient accumulation to simulate a larger batch size.
• Early Stopping: Implemented with a patience of 5 epochs to prevent overfitting.

🛠️ Usage Example

from transformers import MarianMTModel, MarianTokenizer

model_name = "dhintech/marian-tedtalks_clean2-id-en"
tokenizer = MarianTokenizer.from_pretrained(model_name)
model = MarianMTModel.from_pretrained(model_name)

# Pindahkan model ke GPU jika tersedia
import torch
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)

def translate(text):
    inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True, max_length=128).to(device)
    with torch.no_grad():
        outputs = model.generate(**inputs, num_beams=4, early_stopping=True)
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

# Contoh penggunaan
indonesian_text = "Selamat pagi, mari kita mulai rapat hari ini."
english_translation = translate(indonesian_text)
print(f"ID: {indonesian_text}")
print(f"EN: {english_translation}")

🎯 Intended Use Cases

• Presentation Translation: Translating presentation scripts and materials.
• Formal Content: Translating articles, reports, and other formal documents.
• Educational Content: Assisting with the translation of academic and educational materials.

⚡ Performance Metrics

Performance metrics such as BLEU score, inference time, and human evaluation will be added here after the model has been fully trained and evaluated.

🚨 Limitations and Considerations

• Domain Specificity: While trained on a broad corpus, performance is best on formal language similar to TED Talks. It may not perform as well on very casual slang or regional dialects.
• Long Sequences: Performance might degrade for sentences significantly longer than the max length used in training (128 tokens).
