Transformer
A neural network architecture that uses self-attention mechanisms to process sequential data in parallel, revolutionizing NLP and enabling models like GPT and BERT.
Detailed Explanation
Transformers are a breakthrough neural network architecture introduced in 2017 that revolutionized natural language processing. Unlike previous sequential models (RNNs, LSTMs), transformers process all words in a sentence simultaneously using a mechanism called self-attention, which allows each word to 'attend to' and learn relationships with every other word. This parallel processing makes transformers much faster to train and better at capturing long-range dependencies in text. Transformers are the foundation of modern LLMs like GPT, BERT, and Claude, and have expanded beyond NLP to computer vision and multimodal AI.
Real-World Examples
Language Translation
TechnologyGoogle Translate uses transformer models to achieve near-human translation quality across 100+ languages, reducing translation errors by 60% compared to previous approaches.
Code Generation
Software DevelopmentGitHub Copilot uses transformer models to suggest code completions, helping developers write code 55% faster and reducing time spent on repetitive coding tasks.
Frequently Asked Questions
Q:Why are transformers better than RNNs?
Transformers process sequences in parallel (faster training), handle long-range dependencies better (no vanishing gradient), and scale more effectively to large datasets. RNNs process sequentially, making them slower and less effective for long sequences.
