Transformer Block
A neural network architecture component essential for efficiently handling sequential data by capturing long-range dependencies using attention mechanisms.
A transformer block is a critical component within the transformer model architecture, featuring layers of self-attention and feedforward neural networks, which excel at processing sequential data such as text or audio by enabling parallel computation and capturing long-range dependencies. This innovation allows for significant improvements in tasks requiring understanding context across sequences, such as natural language processing (NLP) and neural machine translation, due to its ability to assign different attention weights to different words or tokens, thus enabling comprehensive understanding and generation of language models like BERT and GPT. With its focus on attention mechanisms, the transformer architecture has largely supplanted earlier models like RNNs (Recurrent Neural Networks) for many modern AI tasks, marking a paradigm shift in handling sequence-based data.
The transformer architecture was first introduced in the landmark 2017 paper "Attention is All You Need," rapidly gaining traction and popularity within the AI community due to its demonstrated efficacy on various benchmarks and the success of models built upon it.
Key contributors to the development of the transformer and its foundational block are researchers from Google Brain, including Ashish Vaswani, Noam Shazeer, Niki Parmar, Jakob Uszkoreit, Llion Jones, Aidan N. Gomez, Lukasz Kaiser, and Illia Polosukhin, who collectively authored the seminal paper on the architecture.
