The transformer architecture, introduced in the 2017 paper "Attention is All You Need," revolutionized natural language processing. Unlike previous sequence-to-sequence models that relied on recurrent neural networks, transformers use self-attention mechanisms to process entire sequences in parallel. This enables much faster training and better handling of long-range dependencies. The architecture consists of an encoder and decoder, each made up of multiple layers of self-attention and feed-forward networks. Key innovations include multi-head attention, which allows the model to attend to different positions simultaneously, and positional encoding, which preserves sequence order information. Transformers form the basis of models like BERT, GPT, and T5, which have achieved state-of-the-art results across many NLP benchmarks.
