## Transformer Architecture

In this project, the Transformer architecture from the original 'Attention Is All You Need' paper was built from scratch using PyTorch. The model was specifically trained for English-to-Tamil translation, with each step mathematically explained.

## Technical Details

The project was trained on Kaggle using two NVIDIA T4 GPUs and a parallel translation dataset from Hugging Face. Tensor shape transformations and each PyTorch block were explained step by step.

## Mathematical Explanations

The blog post details every equation in the Transformer, providing a valuable resource for those looking to understand how the model works.

## Code Sharing

The entire project code is shared on GitHub, allowing developers to examine and use the model in their own projects.

## Community Feedback

The developer is open to feedback and questions from the community, which will help further improve the project.

## Translation Technologies

This project serves as a practical example for those interested in understanding how language translation technologies work, showcasing the potential of Transformer models.
