Neural Machine Translation with Attention 🚀

A PyTorch implementation of a Sequence-to-Sequence model with Attention for English-Spanish translation.

🌟 Features

Bidirectional GRU Encoder: Captures context from both directions of the input sequence
Attention Mechanism: Helps the model focus on relevant parts of the input sequence
Teacher Forcing: Implements curriculum learning for better training stability
Dynamic Batching: Efficient training with variable sequence lengths
Hugging Face Integration: Uses MarianTokenizer for robust text processing

🏗️ Architecture

The model consists of three main components:

Encoder: Bidirectional GRU network that processes input sequences
Attention: Computes attention weights for each encoder state
Decoder: GRU network that generates translations using attention context

plaintext

Input → Encoder → Attention → Decoder → Translation
      ↑          ↑          ↑
      Embeddings Context    Attention Weights

🚀 Quick Start

Clone the repository:

bash

git clone https://github.com/yourusername/nmt-attention.git
cd nmt-attention

Install dependencies:

pip install torch transformers datasets

Train the model:

python train.py

Translate text:

python

from translate import translate
text = "How are you?"
translated = translate(model, text, tokenizer)
print(translated)

# Loading a saved model
model = Seq2Seq(encoder, decoder, device)
model.load_state_dict(torch.load('LSTM_text_generator.pth'))
model.eval()

📊 Model Performance

Training metrics after 10 epochs:

Initial Loss: 11.147
Final Loss: 3.527
Training Time: ~2 hours on NVIDIA V100
