Overview
The Transformer model, introduced in the paper Attention Is All You Need, has become a cornerstone of modern NLP. Unlike traditional RNN-based architectures, it relies entirely on attention mechanisms for sequence modeling, enabling parallel processing and scalability.
Key Innovations
Self-Attention Mechanism ✅
Allows the model to weigh the importance of different words in a sentence dynamically.Positional Encoding ✅
Injects information about the position of words in a sequence.Multi-Head Attention ✅
Enhances model performance by aggregating information from different representation subspaces.
Applications
