What is AI Hallucination?
When AI systems generate plausible-sounding but factually incorrect or fabricated information not based on training data.
Definition
AI Hallucination occurs when artificial intelligence systems generate information that appears plausible and coherent but is factually incorrect, fabricated, or not grounded in the training data or real-world facts.
Purpose
Understanding hallucinations is crucial for identifying AI limitations, implementing verification systems, and developing strategies to improve AI reliability and accuracy in factual domains.
Function
Hallucinations happen when AI models fill knowledge gaps with plausible-sounding content, extrapolate beyond their training data, or generate responses based on spurious patterns rather than factual information.
Example
An AI assistant confidently stating that "The Eiffel Tower was built in 1912" (actually 1889) or providing detailed information about a non-existent scientific study with realistic-sounding authors and findings.
