english-marathi-colloquial-translator

This model is a fine-tuned version of unsloth/tinyllama-chat-bnb-4bit on the RutujaPatil29/marathi-model-dataset dataset. It achieves the following results on the evaluation set:

• Loss: 8.7797

Model description

This model is designed to translate English sentences into Marathi with a focus on colloquial language, informal phrases, and slang. Unlike traditional translation models, it understands the nuances of everyday spoken Marathi.

Intended uses & limitations

✅ Handles casual and slang Marathi well
✅ Understands sentence structure and context
⚠️ May struggle with highly formal translations
⚠️ Does not support code-mixing (Hinglish/Marathenglish) yet

Training and evaluation data

Dataset Sources:
The model was fine-tuned on a custom dataset created from:
1️⃣ Scraped articles & text from Marathi news websites (Loksatta, Sakal, Maharashtra Times)
2️⃣ Manually annotated informal translations for better conversational accuracy
3️⃣ Commonly used Marathi slang and spoken phrases

Data Cleaning & Preprocessing:
Removed formal literary phrases to retain conversational style
Tokenized text using SentencePiece/BPE
Aligned informal Marathi with English inputs
Evaluation Metrics:
BLEU Score – Measures translation accuracy
Perplexity (PPL) – Checks model fluency
Human Evaluation – Native Marathi speakers verified outputs
