Seq2Seq
Domain: NLP Fundamentals
🎯 Motivation
Sequence-to-sequence models take an input sequence and produce an output sequence of different length.
📋 Concrete Example
Translation: input 5 Chinese words, output 7 English words. The lengths differ, and that is fine.
🔗 Analogy
Like a translator who reads a 3-line Chinese poem and writes a 4-line English version.
