The Transformer Revolution
The “Attention Is All You Need” paper by Vaswani et al. (2017) changed everything. By dispensing with recurrence and convolutions entirely, the Transformer model relied solely on attention mechanisms to draw global dependencies between input and output.
Key Innovations
- Self-Attention: The model weighs the importance of different words in a sentence regardless of their position.
- Multi-Head Attention: Allows the model to jointly attend to information from different representation subspaces.
- Positional Encoding: Since there is no recurrence, the model must be explicitly informed about the relative or absolute position of the tokens.
Impact
This architecture laid the groundwork for BERT, GPT, and practically every modern LLM. It proved that massive parallelization was possible, unlocking the era of foundation models.
