Hallucination
Domain: NLP Fundamentals
🎯 Motivation
When a language model confidently states false information as if it were true. A major challenge in NLP.
📋 Concrete Example
A model might say Hong Kong was founded in 1843 (wrong, it was 1842) with full confidence.
🔗 Analogy
Like a student who makes up an answer on an exam and writes it confidently - sounds right, but is wrong.
