Decoding the Bridge: How Encoder-Decoder Attention Powers Machine Translation

Encoder-decoder attention is the critical mechanism that allows Transformers to maintain context between input and output sequences, ensuring crucial information isn't lost during translation. Without it, meaning can completely flip—as the article illustrates with the negation 'Don't' being ignored, turning a warning into an invitation. This concept is fundamental to modern machine translation, chatbots, and any AI system that must preserve logical coherence across language or sequence transformations.
