⚙️ Model Description

This model was developed using Assamese text data and trained with a custom tokenizer specifically designed for Assamese script. It uses an LSTM architecture, making it well-suited for capturing the sequence and context of natural language in sentiment classification tasks.

• 📚 Training Data The dataset was curated from public sources such as news articles, social media comments, and feedback forms, and was manually labeled into three sentiment classes: Positive, Neutral, and Negative.

• 🏋️ Training Procedure

• ✂️ Preprocessing: Text cleaning, tokenization using AssameseTokenizer, optional stemming and stopword removal

• 🔢 Input Handling: Sequences padded or truncated to a fixed length of 512 tokens

• 🧠 Architecture: Embedding layer → LSTM → Dense (Softmax)

• 💧 Regularization: Dropout layers to prevent overfitting

• ⚙️ Optimizer: Adam

• 🔁 Epochs: Trained for X epochs (replace with your actual number)

• 📊 Evaluation: Final validation accuracy and F1-score: Insert actual metrics here

📦 Intended Usage

Ideal for:

• 🗨️ Social media sentiment tracking in Assamese

• 📢 Public opinion & brand monitoring

• 📚 Research on low-resource NLP in Indic languages

• ⚠️ Limitations / Not Recommended For:

Code-mixed Assamese-English input

Domain-specific texts (e.g., legal, medical) without additional fine-tuning

🧪 Quickstart: Using the Model

You can load and run the model easily via Hugging Face's transformers pipeline:

from transformers import pipeline

model_name = "niharikanath/assamese-sentiment-analysis"
pipe = pipeline("text-classification", model=model_name, tokenizer=model_name)

result = pipe("এই খাবাৰটা একদম ভালো আছিল!")  # Sample Assamese sentence
print(result)
